International Classification:
C08G 63/91
US Classification:
525419
Abstract:
Compounds are described that have both an aziridinyl group as well as a polymeric group. Methods of making these compounds are also described. The aziridinyl group of the compound can be reacted with an acidic group on a second compound resulting in the opening of the aziridinyl ring and the attachment of the polymeric group to the second compound.

C08F 265/04
US Classification:
525 63, 525 90
Abstract:
Grafted compounds are formed by reacting (1) a first compound having both an aziridinyl group and a polymeric group with (2) a second compound having at least one acidic group. This reaction results in the opening of the aziridinyl ring on the first compound by the acidic group on the second compound and the formation of an attachment group that connects polymeric group of the first compound to the second compound. In some embodiments, the second compound is a polymeric material having multiple acidic groups and the product of the reaction of the first compound with the second compound results in the formation of a grafted copolymer.
