Heat-sealable vulcanizates comprising polyolefin rubber and propylene polymer |
摘要 |
Polyolefin rubber compositions which are readily heat-sealable are provided by the addition of 5-100 parts by weight, based on the polyolefin elastomer, of a propylene polymer uniformly admixed therewith prior to vulcanization which is selected from the group consisting of polypropylene and copolymers of propylene with up to 20% by weight of ethylene, butene-1 or hexene-1 which polymer has a heptane-extractable portion of 5-60%, and I-value measured according to DIN 53 728 of 100-600 cm3/g. and a yield point measured according to DIN 53 735 of 10-30 N/mm2.
