【発明の名称】付加断片化剤の存在での、熱-及び光開始ラジカル重合

Document Type and Number:

Japanese Patent JP2002523529

Kind Code:

A

Abstract:

Disclosed are compositions from which radically initiated oligomers/polymers having a controlled molecular weight, low polydispersity and a vinyl or dienyl end group are prepared. Further subjects of the invention are a process for controlled radical polymerization, oligomers/polymers obtainable by said process and the use of specific addition fragmentation agents for the polymerization process. The addition fragmentation agents are new in part and these are also subject of the present invention. The addition fragmentation agents are of the formula (Ia), (Ib) or (Ic)where Y is a group which activates the double bond towards Michael addition.
