Abstract

Compositions include a compound preparable by reaction of components comprising an optionally crosslinked polyethylenimine and at least one an amine-reactive hydrolyzable organosilane represented by the formula R—Z—SiY3. R represents an amine-reactive group containing 1 to 18 carbon atoms; Z represents a divalent organic group containing 1 to 8 carbon atoms; and each Y independently represents a hydrolyzable group. Methods of using the compositions to make articles, and articles produces thereby are also disclosed. A composition comprising an intimate mixture of a crosslinked polyethylenimine and a polymeric binder material, and a method of making it is also disclosed.

First claim

What is claimed is:

1. A composition comprising a compound preparable by reaction of components comprising a polyethylenimine and at least one an amine-reactive hydrolyzable organosilane represented by the formula:
R—Z—SiY 3

wherein:
R represents an amine-reactive group containing 1 to 18 carbon atoms;
Z represents a divalent organic group containing 1 to 8 carbon atoms; and
each Y independently represents a hydrolyzable group; and

wherein the composition further comprises a polymeric binder material selected from the group consisting of polyvinyl alcohol, hydroxyethyl cellulose, and polymer latexes.

2. The composition of claim 1 , further comprising an aqueous liquid vehicle in which the compound is dispersed or dissolved.

3. The composition of claim 1 , wherein R has from 1 to 3 carbon atoms.

4. The composition of claim 1 , wherein R is selected from the group consisting of an isocyanato group, an oxiranyl group, a glycidoxy group, an acryloxy group, a carboethoxy group, a carbomethoxy group, a vinylsulfonyl group, and an acrylamido group.

5. The composition of claim 1 , wherein Z further contains from 1 to 6 heteroatoms selected from the group consisting of O, N, and S.

6. The composition of claim 1 , wherein Z comprises an alkylene group containing 1 to 3 carbon atoms.

7. The composition of claim 1 , wherein each Y is independently selected from methoxy, ethoxy, hydroxy, acetoxy, chlorine, and bromine.

8. The composition of claim 1 , wherein the at least one an amine-reactive hydrolyzable organosilane is selected from the group consisting of 3-isocyanatopropyltriethoxysilane, 3-isocyanatopropyltrimethoxysilane, 2-isocyanatoethyltriethoxysilane, 2-isocyanatoethyltrimethoxysilane, 3-acryloxypropyltriethoxysilane, 3-acryloxypropyltrimethoxysilane, 2-acryloxyethyltriethoxysilane, 2-acryloxyethyltrimethoxysilane, 2,3-epoxypropyltrimethoxysilane, 2,3-epoxypropyltriethoxysilane, 3-glycidoxypropyltriethoxysilane, and 3-glycidoxypropyltrimethoxysilane.
