Alkylene oxide-modified dipentaerythritol (meth)acrylate and reactive composition containing same

摘要

An alkylene oxide-modified polyfunctional (meth)acrylate is provided wherein the problems according to high crystallinity or high viscosity are improved, and the photosensitivity, etc. is enhanced. 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 —CH₂CH₂O—, —CH₂CH(CH₃)O—, —CH₂CH₂CH₂CH₂O— and —CH₂CH(C₂H₅)O—; l indicating the average polymerization degree of the added alkylene oxide is 0l≤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), R² represents a hydrogen atom or a methyl group.;
