    • 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 following formula: ##STR1## 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.
    • 通过共聚合(A)40〜60摩尔%的N-乙烯基内酰胺和(B)60〜40摩尔%的至少一种含有过氧基的富马酸酯而制备的聚合物型聚合引发剂,所述过氧富马酸酯(B) 其中R 1是含有不超过18个碳原子的直链烷基,支链烷基或环烷基,或含有6-18个碳原子的芳族烃基; 并且R 2是含有不超过13个碳原子的直链烷基,支链烷基或环烷基或苯基。 过氧富马酸酯(b1)可以与(b2)至少一种富马酸二酯组合使用,所述富马酸二酯选自富马酸烷基氟烷基酯,富马酸烷基烷基酯,富马酸烷基烷基酯,富马酸氟烷基酯,富马酸烷基酯,富马酸烷基酯 (氟烷基)富马酸酯和双(含硅 - 烷基)富马酸酯,过氧富马酸与富马酸的二酯的摩尔比在9至1至1至9的范围内。
