ABSTRACT:
It was surprisingly found that a thermoplastic molding composition which contains polycarbonate and polyalkylene terephthalate resins at a particular weight ratio therebetween is rendered improved impact strength and hydrolysis resistance upon the incorporation of an additive amount of high melt flow high density polyethylene therewith. The molding composition of the invention comprise about 20-90 percent of polycarbonate resin, 80-10 percent of polyalkylene terephthalate (preferably PET) and about 3 to 5 percent of a high density polyethylene resin having a specific gravity of 0.94-0.97 and melt flow of 1 to 80 gm/10 min. as determined in accordance with ASTM D 1238.
