Abstract
AbstractIn a system initiated by potassium persulfate, an ultra‐cold‐resistant reactive chlorinated resin rubber was synthesized by emulsion polymerization. In this emulsion polymerization, ethyl acrylate and butyl acrylate were used as the main components of the rubber monomer. 2‐Methoxyethyl acrylate was used as a cold‐resistant monomer, and vinyl chloroacetate was used as a vulcanized monomer. Fourier transform infrared spectroscopy, thermogravimetry–gas chromatography–mass spectrometry, 1H NMR, 13C NMR and other rubber detection standards were used to characterize the structure and properties of the synthetic acrylate rubber. Studies showed that acrylate rubber was synthesized by emulsion polymerization, and each monomer achieved random copolymerization with high conversion. The synthetic acrylate rubber has excellent low‐temperature resistance (the brittleness temperature is −36.5 °C). In addition, the rubber has excellent mechanical properties and a high vulcanization speed and is a fast‐vulcanizing acrylic rubber. © 2022 Society of Industrial Chemistry.
