Thermal degradation of copolymers based on selected alkyl methacrylates

Abstract

The thermal stability and thermal degradation of copolymers based on selected alkyl methacrylates at temperatures between 250 and 400 °C have been studied using pyrolysis–gas chromatography. The type and composition of thermal degradation products gave useful information about the mechanism of pyrolysis of copolymers synthesized by using typical commercially available alkyl methacrylates. It was observed that the main thermal degradation products from alkyl methacrylate copolymers are monomers of alkyl methacrylates using by synthesis. Other pyrolysis by-products formed during thermal degradation were carbon dioxide, carbon monoxide, methane, ethane, methanol, ethanol, and propanol-1.
