| titleOfInvention |
Block copolymers of ethylene and propylene and process for their manufacture |
| abstract |
Novel compositions of block copolymers of ethylene and propylene and processes therefor which compositions exhibit improved oriented film shrink properties, improved processability and improved uniformity in gauge when extruded and oriented into films and which exhibit improved impact strenght, improved low temperature brittleness properties and improved parison stability when molded as compared to prior art processes. The compositions comprise: A. 60% TO 96% BY WEIGHT OF A PREPOLYMER BLOCK OF A RANDOM COPOLYMER OF (1) 90 TO 99 MOLE PERCENT OF PROPYLENE AND 1 TO 10 MOLE PERCENT OF ETHYLENE, AND B. 4% TO 40% BY WEIGHT OF A POST BLOCK OF A RANDOM COPOLYMER OF (1) 70 TO 99 MOLE PERCENT OF PROPYLENE AND 1 TO 30 MOLE PERCENT OF ETHYLENE. |
