Abstract
Oxazolinyl-containing compounds having a single oxazolinyl group plus a first polymeric group are described. Grafted compounds are also described that are the product of a reaction of an oxazolinyl-containing compound with a second compound that has one or more acidic groups to form a grafted compound. In some embodiments, the second compound is a polymeric material having at least one acidic group and the reaction product is a grafted copolymer. Blended compositions of the grafted copolymer with a polyamide are also described.
