Title:
ORGANOZINC COMPOUND PRODUCING METHOD, CHAIN TRANSFER AGENT, BLOCK COPOLYMER, AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/025701
Kind Code:
A1
Abstract:
The present invention relates to a chain transfer agent containing an organozinc compound, a method for preparing same, and a method for preparing a block copolymer using same. A chain transfer agent is obtained by a preparation method comprising the steps of: preparing a Grignard reagent containing a styrene residue; and reacting the prepared Grignard reagent with an alkyl zinc alkoxide as a zinc compound, and has no catalyst poison and byproducts and contains 96 wt% or more of a target compound. A block copolymer obtained by polymerization using the chain transfer agent and a resin composition comprising the block copolymer have excellent mechanical properties.
