ABSTRACT:
Graft polymers are prepared by the free radical reaction of a base polymer such as polyethylene or polypropylene with an olefinic compound containing a tertiary alkyl ester group, which may be a simple carboxylic acid or a carbamic acid ester group. Upon melt blending or the like with polymers containing other functional groups, such as carboxy- or epoxy-functionalized polyphenylene ethers, the t-butyl groups are removed by thermal degradation and there are obtained copolymers which are useful to compatibilize blends of the corresponding polymeric constituents.
