Vinyl-Benzyl Ethers Of Phenol-Dicyclopentadiene Adducts As New Thermosetting Resins For Composites

US Patent:

4824920, Apr 25, 1989

Filed:

Nov 30, 1987

Appl. No.:

7/126312

Inventors:

Joseph J. Zupancic - Bensenville IL
Jeffrey P. Conrad - Chicago IL
James A. Wrezel - Buffalo Grove IL
Andrew M. Zweig - Schaumburg IL
Jean M. J. Frechet - Ithica NY

Assignee:

Allied-Signal Inc. - Morristown NJ

International Classification:

C08G 6112

US Classification:

525534

Abstract:

The resins resulting from converting dicyclopentadiene-phenol adducts to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from therma, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.

Ethers Of The Condensation Products Of Phenoldicyclopentadiene Adducts With Aldehydes And Ketones As Thermosetting Resins

US Patent:

4804721, Feb 14, 1989

Filed:

Nov 30, 1987

Appl. No.:

7/126378

Inventors:

Joseph J. Zupancic - Bensenville IL
Jeffrey P. Conrad - Chicago IL

Assignee:

Allied-Signal Inc. - Morristown NJ

International Classification:

C08G 836, C08G 830, C08G 802

US Classification:

525502

Abstract:

The resins resulting from converting the phenol-formaldehyde type condensation products of dicyclopentadiene-phenol adducts with selected aldehydes and ketones to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from thermal, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.

Solvent Free Epoxy Resin Compositions Containing Substituted Cyanoguanidines

US Patent:

5534565, Jul 9, 1996

Filed:

Apr 15, 1994

Appl. No.:

8/227915

Inventors:

Joseph J. Zupancic - Bensenville IL
Jeffrey P. Conrad - Chicago IL
Jiri D. Konicek - Onalaska WI
Aroon V. Tungare - Arlington Heights IL

Assignee:

AlliedSignal Inc. - Morris Township, Morris County NJ

International Classification:

C08L 6302

US Classification:

523454

Abstract:

Epoxy resin compositions used in preparation of laminates for electronic applications are free of the solvents typically needed in current industrial practice. The use of certain mono-substituted dicyandiamides makes possible the elimination of such solvents since all of the components are soluble in epoxy resin to an extent which provides uniform properties in the cured laminates.

Substituted Cyanoguanidines As Curing Agents For Epoxy Resins

US Patent:

5387656, Feb 7, 1995

Filed:

Nov 16, 1993

Appl. No.:

8/153401

Inventors:

Joseph J. Zupancic - Bensenville IL
Jeffrey P. Conrad - Chicago IL

Assignee:

AlliedSignal Inc. - Morris Township, Morris County NJ

International Classification:

C08L 6302

US Classification:

525523

Abstract:

A curing agent for epoxy resins having improved solubility characteristics has the formula ##STR1## where R is --CH. sub. 2 C. sub. 6 H. sub. 4 X or --CH. sub. 2 CH. sub. 2 C. sub. 6 H. sub. 4 X, and X is either --H, --CH. sub. 3, --OCH. sub. 3, --OH, or --NY, and where Y is --H or CH. sub. 3. Such substituted cyanoguanidines are soluble in various solvents and do not require the use of undesirable solvents necessary with cyanoguanidine (dicyanodiamide) itself.

Complete Ether Capping Of Oligomeric Polyphenols

US Patent:

4871831, Oct 3, 1989

Filed:

Nov 30, 1987

Appl. No.:

7/126314

Inventors:

Andrew M. Zweig - Schaumburg IL
Jeffrey P. Conrad - Chicago IL

Assignee:

Allied-Signal Inc. - Morristown NJ

International Classification:

C08G 6338

US Classification:

528205

Abstract:

A method is presented to prepare totally functionalized ether-capped oligomeric polyphenols without molecular weight fractionation. The products generally are very low in inorganic salts and are characterized by the absence of volatiles leading to void formation in their subsequent curing. The success of the method rests upon conducting the reaction under totally homogeneous conditions throughout.

Ethers Of Oligomeric Phenol-Diketone Condensation Products And A Vinyl-Benzyl Compound

US Patent:

4921923, May 1, 1990

Filed:

Nov 18, 1988

Appl. No.:

7/272954

Inventors:

Joseph J. Zupancic - Bensenville IL
Jean M. J. Frechet - Ithaca NY
Andrew M. Zweig - Schaumburg IL
Jeffrey P. Conrad - Chicago IL

Assignee:

Allied Signal Inc. - Morris Township, Morris County NJ

International Classification:

C08G 202, C08G 234, C08G 802, C08G 836

US Classification:

526313

Abstract:

Oligomeric condensation products of certain diketones and phenols can be end-capped with a vinylbenzyl moiety and certain other moieties, especially alkyl groups, to afford thermosetting resins particularly valuable in making laminated circuit boards. Resins prepared by the reaction of 1 molar proportion of diacetylbenzene with from 3. 5 to 4. 0 molar proportions of phenol and end-capped with from 50 to 100% vinylbenzyl groups with the remainder being alkyls of 1 through 11 carbon atoms are particularly useful.

C07F 708

US Classification:

556460

Abstract:

This invention relates to an improved, high-yield process for producing cyclic siloxane in a biphasic reaction solvent mixture comprising an alkane, an alcohol and water.
