Elastomer composition tough flexible from the semi-crystalline amorphous polyolefin block copolymers

摘要

Polyolefin block and graft copolymer, it those of can be mixed in low molecular weight fluid diluent by two or more semicrystalline polyolefin blocks or grafting and one or more amorphous polyolefin blocks and preferentially position and expand the block or graft copolymer of non-domain, while keep the semi-crystalline block domain of crystallinity. By being mechanically or thermally machined, this composition, which combines flexibility, has high-intensitive and high recoverable elasticity. Also disclosing composition, thus diluent material is being machined before composition or mechanically or thermally, to generate strong elasticity material with ultralow entanglement density in amorphous domain.
