Abstract

In this study, it was studied the relationship between the chemical structures of acrylate monomers and their thermal stability. To prepare the co-polymers based on acrylate monomer, emulsion polymerization was performed using with an initiator of AIBN (azobisisobutyronitrile). The thermal stability of the prepared copolymers was evaluated as a weight reduction rate by a thermogravimetric analyzer (TGA), and the molecular weight distribution of synthesized copolymers was analyzed by using a gel permeation chromatography (GPC). The hydrogen bond length and charge distribution caused by intermolecular interactions were simulated. The copolymerization of n-butyl acrylate and 2-chloroethyl vinyl ether resulted in a weight reduction of 0.41%, and an average molecular weight of 1,108,000.
