Patent ID: 8450452

Claim:
A composition comprising a polymeric reaction product of at least a polyamine, a first nitrogen-reactive compound, and a second nitrogen-reactive compound, the polymeric reaction product having a weight average molecular weight of at least about 500, wherein: the polyamine is selected from polyethyleneimine and triethylenetetramine; the first nitrogen-reactive compound comprises a —Si(OR″) 3 group and a nitrogen-reactive group, where R″=═H, optionally substituted C 1 -C 20 alkyl, optionally substituted C 6 -C 12 aryl, optionally substituted C 7 -C 20 aralkyl, optionally substituted C 2 -C 20 alkenyl, Group I metal ion, Group II metal ion, or NR 1 4 , each R 1 being independently selected from H, optionally substituted C 1 -C 20 alkyl, optionally substituted C 6 -C 12 aryl, optionally substituted C 7 -C 20 aralkyl, and optionally substituted C 2 -C 20 alkenyl, the first nitrogen-reactive compound is selected from glycidoxypropyl trimethoxysilane and chloropropyl trimethoxysilane; the second nitrogen-reactive compound comprises a nitrogen-reactive group and does not contain a Si(OR″) 3 group, the second nitrogen-reactive compound is selected from dimethylsulfate, chlorooctane, chlorohexane, benzyl chloride, epichlorohydrin, glycidyl 4-nonylphenylether, butyl glycidyl ether, 2-ethylhexyl glycidyl ether, phenyl glycidyl ether, C 12 -C 14 alkyl glycidyl ether, cresyl glycidyl ether, octenylsuccinic anhydride and octadecenylsuccinic anhydride; and at least one of the polyamine and the second nitrogen-reactive compound comprises an optionally substituted hydrocarbyl radical comprising from about 2 to about 40 carbons.
