Abstract

An iodine compound represented by formula (3) and a polymerization inhibitor including the iodine compound, wherein R21 to R25 are as defined herein, X1 is an n1-valent group, and n1 is an integer of 1 to 10:

First claim

What is claimed is:

1. A compound represented by formula (3):

wherein
X 1 is an n1-valent siloxane group;
R 21 is H, F, Cl, CH 3 , CF 3 , or O(CF 2 ) p3 F;
R 22 is —R 26 —OCO— wherein R 26 is bonded to X 1 ;
R 23 is H or F;
R 24 is H, F, an aryl group, —COOR 30 , or an alkyl group optionally substituted with fluorine;
R 25 is H, F, an aryl group, —COOR 30 , or an alkyl group optionally substituted with fluorine;
R 26 is a single bond or an alkylene group optionally substituted with fluorine;
R 30 is H or an alkyl group;
p3 is an integer of 1 to 10; and
n1 is an integer of 1 to 10,
wherein the siloxane group is represented by the following formula:
—(SiR 27 2 —O) q —SiR 27 2 —,
—SiR 28 r R 29 3-r , or
(R a SiO 1.5 ) t

wherein
R 27 , each independently at each occurrence, is a hydrogen atom or an alkyl group;
R 28 , each independently at each occurrence, is —O—(SiR 27 2 —O) s —SiR 27 3 —;
R 29 is a single bond;
R a , each independently at each occurrence, is R b or R c , provided that
at least one R a is R b ,
R b is a single bond, and
R c is a hydrogen atom or alkyl;
q is an integer of 1 to 20;
r is an integer of 1 to 3;
s is an integer of 0 to 20; and
t is any integer.

2. A polymerization initiator comprising the compound according to claim 1 .
