PHOTOACTIVATABLE CHAIN TRANSFER AGENT

摘要

PROBLEM TO BE SOLVED: To provide a novel photoactivatable reagent relating to the field of reagent such as chain transfer agent, useful for controlling the molecular weight of synthetic polymers. SOLUTION: The photoactivatable reagent is useful as a chain transfer reagent for providing a semitelechelic polymer having one or more terminal photoactivatable groups. The chain transfer reagent provides one or more photoactivatable groups and one or more sulfhydryl groups (or other chain transfer groups), the photoactivatable and chain transfer groups optionally being joined together by a spacer group. The reagent can be used to prepare a polymer by serving to initiate the polymerization of ethylenically unsaturated monomers. COPYRIGHT: (C)2005,JPO&NCIPI
