【発明の名称】ポリマー型重合開始剤
Document Type and Number:
Japanese Patent JP2778770
Kind Code:
B2
Abstract:
A polymer-type polymerization initiator produced by copolymerizing (A) 40 to 60 mole % of an N-vinyllactam and (B) 60 to 40 mole % of at least one fumarate containing a peroxy group, the peroxy-fumarate (B) being represented by the formula (I): wherein R1 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 18 carbon atoms, or an aromatic hydrocarbon group containing 6 to 18 carbon atoms; and R2 is a linear alkyl, branched alkyl or cycloalkyl group containing not more than 13 carbon atoms, or a phenyl group. The peroxy-fumarate (b1) may be used in combination with (b2) at least one diester of fumaric acid selected from the group consisting of alkyl fluoroalkyl fumarate, alkyl silicon-containing-alkyl fumarate, fluoroalkyl silicon-containing-alkyl fumarate, bis(fluoroalkyl) fumarate, and bis(silicon-containing-alkyl) fumarate, a mole ratio of the peroxy-fumarate to the diester of fumaric acid falling within a range of 9 to 1 to 1 to 9.
