More Information
Summary:The present invention relates to a chain transfer agent comprising an organozinc compound, a method for preparing the same, and a method for preparing a block copolymer using the same. The chain transfer agent is prepared by a preparation method including preparing a Grignard reagent containing styrene residues and reacting the prepared Grignard reagent with an alkylzinc alkoxide as a zinc compound, and contains 96 wt% or more of a target compound without catalyst poisons and by-products. The block copolymer polymerized using the chain transfer agent and the resin composition comprising the block copolymer have excellent mechanical properties. 本发明涉及包含有机锌化合物的链转移剂、其制备方法以及使用其制备嵌段共聚物的方法。链转移剂通过包括制备含苯乙烯残基的格氏试剂和将制备的格氏试剂与作为锌化合物的烷基锌醇盐反应的制备方法制备，无催化剂毒物和副产物，含有96重量％以上的目标化合物。使用该链转移剂聚合的嵌段共聚物和包含该嵌段共聚物的树脂组合物具有优异的机械性能。
