Reactive composition comprising alkylene oxide-modified dipentaerythritol acrylate

摘要

To provide an alkylene oxide-modified polyfunctional (meth)acrylate wherein the problems according to high crystallinity or high viscosity, such as bad handleability and high cure shrinkage factor are improved, and the photosensitivity, surface hardness, contamination resistance, etc. are enhanced; and a reactive composition containing the same. The compound has a structure represented by the following formula (I), provided that in the formula (I), R represents a substituent represented by the formula (II); AO represents one member or two or more members selected from alkylene oxide units represented by -CH 2 CH 2 O-, -CH 2 CH(CH 3 )O-, -CH 2 CH 2 CH 2 CH 2 O- and -CH 2 CH(C 2 H 5 )O-; 1 indicating the average polymerization degree of the added alkylene oxide is 01‰¤5; the average value of m is more than 0 and 6 or less; each of the average values of n and o is from 0 to 6, the total value of m, n and o is 6, and in the formula (II), R 2 represents a hydrogen atom or a methyl group.
