Synthesis and Characterization of Carboxyl-containing Acrylate Rubber
摘要
Abstract
Carboxyl-containing acrylate rubber was synthesized with ethyl acrylate and butyl acrylate as main monomers,and acrylic acid as crosslinking-point monomer via semi-continuous seeded emulsion polymerization method. The effect of the amount of acrylic acid on the monomer conversion in emulsion polymerization was stud-ied,the structure of carboxyl-containing acrylate rubber was characterized with FT-IR and DSC,and the mechani-cal properties of the vulcanized rubber were also measured. The results showed that the addition of acrylic acid was beneficial for the increase of monomer conversion,and the glass transition temperatures of the obtained acry-late rubber increased with the amount of acrylic acid increasing. 1 # vulcanizing agent and di-o-tolylguanidine could effectively accelerate the vulcanization of carboxyl-containing acrylate rubber. When the amount of acrylic acid was 4%, the tensile strength and break at elongation of the vulcanized rubber reached to 5. 8 MPa and 606%,respectively.关键词
