Polyurethane Dispersion (Pud) With Improved Isopropanol Resistance, Flexibility And Softness

US Patent:
2004021, Oct 21, 2004
Filed:
Oct 2, 2003
Appl. No.:
10/677882
Inventors:
Eduard Mayer - Dormagen, DE
Thomas Muenzmay - Dormagen, DE
Yuliya Berezkin - Pittsburgh PA, US
Poli Yu - Wexford PA, US
Richard Roesler - Wexford PA, US
Mary Crisci - Aliquippa PA, US
International Classification:
C08G018/00, C08G018/10, C08G018/32
US Classification:
528/059000, 528/076000, 528/068000
Abstract:
Isocyanate-functional polyurethane prepolymers and aqueous dispersions therefrom which are useful for the production of flat materials having excellent resistance to alcoholic solvents are described. The prepolymers are prepared by reacting: A) an isocyanate selected from the group consisting of i) an aliphatic and/or a cycloaliphatic isocyanate, ii) a mixture of an aromatic isocyanate and an aliphatic and/or a cycloaliphatic isocyanate, B) a di- or polyhydroxy compound having a number average molecular weight of from 700 to about 16,000, and C) optionally, a dihydroxy and/or polyhydroxyl compound having a number average molecular weight of less than 700, with the provisos that a) at least one of components A), B or C) has a functionality of more than 2 and b) if both component A) and component B) are difunctional, component C) cannot be a trihydroxy component of the formula:  where R is a saturated straight chain or branched chain aliphatic group of from 2 to 8 carbon atoms.

Modified Polyurethanes

US Patent:
2004024, Dec 9, 2004
Filed:
Jun 3, 2003
Appl. No.:
10/453755
Inventors:
Lyubov Gindin - Pittsburgh PA, US
Richard Roesler - Wexford PA, US
Poli Yu - Wexford PA, US
Joseph Kleer - Crescent PA, US
Thomas Muenzmay - Dormagen, DE
Yuliya Berezkin - Pittsburgh PA, US

International Classification:
C08G018/00, C08G018/32, C08G018/38, C08G018/40, C08G018/10
US Classification:
528/059000, 528/085000
Abstract:
The present invention relates to isocyanate functional prepolymers, aqueous polyurethane dispersions produced from the prepolymers and various uses of such dispersions. The prepolymers are prepared by reacting a diisocyanate, a dihydroxy compound having a number average molecular weight of from about 700 to about 16,000, and a trihydroxy component of the formula: where R is a saturated straight chain or branched chain aliphatic group of from 2 to 8 carbon atoms. The invention also relates to polyurethane dispersions prepared from the prepolymers and to various uses of the resultant dispersions.

Modified Polyurethanes

US Patent:
2006002, Jan 26, 2006
Filed:
Aug 19, 2005
Appl. No.:
11/208321
Inventors:
Lyubov Gindin - Pittsburgh PA, US
Richard Roesler - Wexford PA, US
Poli Yu - Wexford PA, US
Joseph Kleer - Crescent PA, US
Thomas Muenzmay - Dormagen, DE
Yuliya Berezkin - Pittsburgh PA, US

International Classification:
C08G 18/08
US Classification:
524589000
Abstract:
The present invention relates to isocyanate functional prepolymers, aqueous polyurethane dispersions produced from the prepolymers and various uses of such dispersions. The prepolymers are prepared by reacting a diisocyanate, a dihydroxy compound having a number average molecular weight of from about 700 to about 16,000, and a trihydroxy component of the formula: R—(OH) where R is a saturated straight chain or branched chain aliphatic group of from 2 to 8 carbon atoms. The invention also relates to polyurethane dispersions prepared from the prepolymers and to various uses of the resultant dispersions.
