α-(unsaturated alkoxyalkyl) acrylate composition and process for production thereof

摘要

An α-(unsaturated alkoxyalkyl)acrylate composition is provided which enables an α-(unsaturated alkoxyalkyl)acrylate product to be stored at a high purity for an extended period of time and can fully suppress problems such as discoloration and gelation from arising during polymerization, and a method of safely preparing α-(unsaturated alkoxyalkyl)acrylate compositions industrially, with high purity. The composition includes an α-(unsaturated alkoxyalkyl)acrylate of a specific structure and an antioxidant, the content of the antioxidant being from 0.03 to 0.5 wt % per 100 wt % of the α-(unsaturated alkoxyalkyl)acrylate.

主权项

1. An α-(unsaturated alkoxyalkyl)acrylate composition comprising: an α-(unsaturated alkoxyalkyl)acrylate represented by general formula (1) belowwhere R2, R3 and R4 are identically or independently a hydrogen atom or a C1-30 organic group;
R5 and R6 are identically or independently a hydrogen atom or a C1-18 alkyl group which may be substituted; and Z is an n-valent organic group, with n being an integer greater than or equal to 1; and an antioxidant,
wherein the antioxidant content is from 0.03 to 0.5 wt. % relative to 100 wt. % of the α-(unsaturated alkoxyalkyl)acrylate; andwherein the composition has a nitrogen content, per 100 wt. % of the α-(unsaturated alkoxyalkyl)acrylate, of 100 ppm or less.
