Abstract

A continuous process for the reactive compatibilization of polymers includes I. processing monooxazoline, bisoxazoline or a mixture thereof together with a first polymer, to give a reactive polymer; and II. adding the reactive polymer to one or more second polymers. In addition, a reactive polymer contains I. a first polymer; and II. at least 5% by weight of chemically unbound monooxazoline, bisoxazoline or a mixture thereof.
