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 crosslinked polyethylenimine and at least one 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 crosslinked polyethylenimine comprises a reaction product of a polyamine and a crosslinker represented by the formula
R—Z—R

wherein each of R and Z is independently as previously defined, wherein the composition further comprises a polymeric binder material selected from the group consisting of polyvinyl alcohol, hydroxyethyl cellulose, and polymer latexes and wherein the composition further comprises an aqueous liquid vehicle in which the compound is dispersed or dissolved.

2. An article comprising:
a substrate having a surface; and
a reaction product of a composition comprising a compound preparable by reaction of components comprising a crosslinked polyethylenimine and at least one 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 crosslinked polyethylenimine comprises a reaction product of a polyamine and a crosslinker represented by the formula
R—Z—R

wherein each of R and Z is independently as previously defined, wherein the composition further comprises a polymeric binder material selected from the group consisting of polyvinyl alcohol, hydroxyethyl cellulose, and polymer latexes and at least a portion of the surface of the substrate, and wherein the crosslinked polyethylenimine is a reaction product of polyethyleneimine and an acrylic monomer having at least two acryl groups.

3. A composition comprising an intimate mixture of a crosslinked polyethylenimine and a polymeric binder material, wherein the polymeric binder material is selected from the group consisting of polyvinyl alcohol, hydroxyethyl cellulose, and polymer latexes, and wherein the crosslinked polyethylenimine is a reaction product of polyethyleneimine and an acrylic monomer having at least two acryl groups.

4. The composition of claim 3 , wherein the crosslinked polyethylenimine and the polymeric binder material are dispersed or dissolved in an aqueous liquid vehicle.

5. A method of making a composition, the method comprising sequentially intimately mixing:
an aqueous solution of polyethylenimine;
a crosslinker for the polyethylenimine; and
a polymeric binder material, wherein the polymeric binder material is selected from the group consisting of polyvinyl alcohol, hydroxyethyl cellulose, and polymer latexes, and wherein the crosslinker for the polyethylenimine comprises an acrylic monomer having at least two acryl groups.
