摘要：
A composition comprising the reaction product resulting from subjecting to grafting and esterification reaction conditions a mixture comprising a polyoxyalkylene amine and a vinyl monomer. The mixture is substantially free of copolymers derived from a polyoxyalkylene glycol and a diglycidyl ether, and the reaction product is partially cross-linked. Methods of use and preparation of such compositions are also disclosed.
