Halogenated Ethylene Polymers With Improved Resistance To Agglomeration
US Patent:
4767823, Aug 30, 1988
Filed:
Aug 1, 1986
Appl. No.:
6/894441
Inventors:
Edward Jones - Baton Rouge LA

Assignee:
The Dow Chemical Company - Midland MI
International Classification:
C08F 820
US Classification:
5253341
Abstract:
Halogenated polyethylene resins and halogenated ethylene polymer resins having a reduced tendency to "block" are provided. The halogenated resins are prepared respectively from polyethylene and ethylene polymer starting materials which have a weight-based median particle size of from about 120 to about 600 microns and a weight-based particle size distribution such that more than 60 percent of the particles have a particle size of from about 130 to about 850 microns. The halogenated resins also have a weight-based median particle size of from about 200 to about 900 microns. The halogenated polyethylene resins have a chemically combined halogen content of from about 26 to about 42 weight percent whereas the halogenated ethylene polymer resins have a chemically combined halogen content of from about 15 to about 28 weight percent. The halogenated ethylene polymer resins are prepared from ethylene polymer starting materials which have polymerized therein up to five weight percent of 1-olefin monomer copolymerizable with ethylene.
Chlorinated Polyethlene Mastic Adhesive Compositions, And Process For The Production Of These Compositions
US Patent:
5216053, Jun 1, 1993
Filed:
Nov 27, 1990
Appl. No.:
7/619283

Edward Jones - Baton Rouge LA

Assignee:

International Classification:
C08K 515
US Classification:
524114
Abstract:
Chlorinated polyethylene mastic adhesive compositions, and process for the production of such compositions, formed from chlorinated polyethylene and a compatible plasticizer. These mastic compositions are useful for bonding and sealing together membranes, particularly chlorinated polyethylene membranes, at ambient conditions without application of heat. The ability to form seals of high peel strength in roofing applications without the use of heat is of particular importance. In another embodiment however, cross linking agents can be incorporated within the recipe, and seals of even greater peel strength obtained. Heat is required in the sealing operation in this instance to produce cross linking of the polymer. One thus has the choice of forming adhesives of high peel strength for roofing applications without any necessity of using heat; or, alternatively, to form adhesives of even greater peel strength with the use of heat.
