Title:
REGENERATED METHYL(METH)ACRYLATE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/053545
Kind Code:
A1
Abstract:
The present invention addresses the problem of realizing a high recovery rate even when the raw material supply rate is particularly high. The present invention pertains to a regenerated methyl(meth)acrylate production method comprising: a thermal decomposition step for thermally decomposing a methyl(meth)acrylate-based polymer composition that contains one or more methyl(meth)acrylate-based polymers and includes a methyl(meth)acrylate-based polymer having a viscosity average molecular weight of 800000-5000000; and a recovery step for recovering a regenerated methyl(meth)acrylate generated in the thermal decomposition step.
