摘要:
Compositions of matter useful in the preparation of film which is soft and has high tensile, tear and impact strength. The compositions comprise polyolefin plastics blended with an elastomeric plasticizer; the latter comprises polyethylene or a copolymer of ethylene and an unsaturated ester of a lower carboxylic acid, olefinic elastomer and hydrocarbon oil.
