Title:
METHYL METHACRYLATE-CONTAINING COMPOSITION AND METHYL METHACRYLATE POLYMER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/230913
Kind Code:
A1
Abstract:
The present invention aims to provide a methyl methacrylate-containing composition that has high product quality stability during storage. The problem is solved by a methyl methacrylate-containing composition that includes: a methyl methacrylate; an α, β–unsaturated carbonyl compound indicated in formula (1); and a polymerization inhibitor. The concentration of the methyl methacrylate is 99%–99.99% by mass.
