| 摘要 |
The present invention relates to a curable polymeric composition comprising (i) a thermoplastic block copolymer containing at least two polymer blocks A separated by at least one polymer block B, wherein polymer block A is primarily a poly(monovinyl aromatic hydrocarbon) block or primarily a poly( C3-C7 alkenoic acid ester) block, and polymer block B is primarily an aliphatic elastomeric polymer block; (ii) a radically polymerisable compound that is at least partially compatible with polymer blocks A, and not compatible with polymer block B, wherein the weight percentage of radically polymerisable compound is in the range from 0.1 to 3 times the weight percentage of polymer blocks A, where both weight percentages are basis the total of block copolymer and radically polymerisable compound; and (iii) a radical initiator that is at least partially compatible with the polymer blocks A and/or the radically polymerisable compound, and not compatible with polymer block B. The present invention further relates to a process for the preparation of a cured polymeric composition; to a cured polymeric composition; to a block copolymer obtainable by curing the curable polymeric composition; to a thermoplastic blend containing the curable polymeric composition or the cured polymeric composition and a polyolefin; and to articles containing any one of the above compositions. |
