ABSTRACT:
Polymers containing glutarimide units and also acid and/or anhydride units are compatible with polyesters, such as poly(ethylene terephthalate) to form blends. Chemical interaction (grafting) between the polyester and the acid/anhydride groups of the polyglutarimide occurs on processing the blends. The extent of grafting and the properties of the resultant blend can be enhanced by appropriate catalysts.
