POLYMER COMPOSITIONS HAVING IMPROVED MELT STRENGTH

摘要

Disclosed is a polymeric composition having improved melt strength comprising (a) a polyester containing repeat units from at least 90 mol % terephthalic acid and 90 to 100 mol % ethylene glycol, the polyester having a weight average molecular weight of 75,000-85,000, (b) a polymeric material containing at least 5 wt % polycarbonate and up to 95 wt % polyethylene terephthalate, and (c) a functional additive.
