【Abstract】 Acrylate Interpenetrating polymer network (IPN) was prepared by multistage emulsion polymerization.At first,the polymer network of soft monomer (EA) was synthesized by two step emulsion polymerization,and then the hard monomer (St) and cross linking agent were added into seed emulsion to swell and polymerized by using redox initiator.The effect of EA/St ratio,amount of crosslinking agent added and polymerization conditions on polymerization stability of emulsion and conversion were investigated.After determination of Tg and processability of the IPN gained,a new type of Acrylate TPE with better mechanic properties was obtained.更多还原
