Abstract
Reinforced, molding compositions having improved ductility and melt flow properties. The present compositions contain a cyclo aliphatic polyester resin preferably comprising the reaction product of a cycloaliphatic C.sub.6 -C.sub.12 diol or chemical equivalent and C.sub.6 -C.sub.12 cycloaliphatic diacid or chemical equivalent, preferably an impact modifying amorphous resin which increases the ductility of the polyester resin but reduces the melt flow properties thereof, a high molecular weight polyetherester polymer which increases the melt flow properties of the polyester polymer without reducing the ductility thereof, and a glass filler to reinforce and stiffen the composition and form a reinforced molding composition.
