HIGHLY FILLED, PROPYLENE-ETHYLENE COPOLYMER COMPOSITIONS

摘要

Compositions comprising, based on the weight of the composition: A. Less than 50 wt% of a propylene-ethylene copolymer comprising between 8 and 20 wt% of units derived from ethylene, based on the total weight of the copolymer; B. At least 50 wt% of a filler; and C. Between greater than zero and 1 wt% of a titanate compound. The propylene-ethylene copolymer typically has a low crystallinity of between greater than zero and 35%, and the filler is typically an inorganic material such as aluminum trihydrate and/or calcium carbonate. Mono-alkoxy-titanate is representative of the titanate compounds that can be used in this invention.
