AI Technical Summary
Existing methods for recycling polymethyl(meth)acrylate do not adequately address the need for improving the quality, particularly heat resistance, of recycled materials, and there is a lack of optimization in the composition of raw material monomers to enhance the properties of polymethyl(meth)acrylate.
A composition containing methyl methacrylate, methyl pivalate, and methyl methylbutenoate, with specific concentration ranges, is used to produce polymethyl methacrylate, which includes recycled and bio-derived methyl methacrylate, along with optional additives to enhance heat resistance and durability.
The resulting polymethyl methacrylate exhibits improved heat resistance, as indicated by higher 5% weight loss temperature and glass transition temperature, with reduced residual MMA concentration, leading to superior durability and thermal stability.
