Abstract

Abstract Amino substituted polymeric polyols are produced through Group VIII metal catalytic amination of polymers comprising ethylenically unsaturated alcohols and copolymers of said alcohols and vinyl compounds. Polyamines produced by the amination of polyols and/or copolymers thereof having pendant amino and hydroxyl groups or polyamines having said groups fixed to pendant methylene groups are represented by the general formula: <IMAGE> WHERE R is hydrogen or an acyl group; R', R'' are hydrogen or an alkyl group N IS AN INTEGER AND M, P AND W ARE INTEGERS OF 1 OR MORE; AND <IMAGE> +tr <IMAGE> WHERE R and R' are hydrogen or an alkyl group, M IS AN INTEGER N, P, AND I W ARE INTEGERS OF ONE OR MORE.
