제목 Semibatch emulsion polymerizations of alkyl acrylate copolymers in radox initiation systems
초록 The alkyl acrylate copolymer (ACM) rubbers were synthesized and analyzed with various initiator and reducing agent contents at various temperatures. Ethyl acrylate (EA), butyl acrylate (BA), and methoxyethyl acrylate( MEA) were used as comonomers and 2-chloroethyl acrylate as functional monomer. Tetramethyl ethylene diamine (TMEDA) and potassium persulfate (KPS) were used as oxidant and reducing agent, respectively. The rate of polymerization (Rp) increased and the Mooney viscosity decreased with the increased amount of KPS. When the initiator concentration was smaller than 0.4 wt.% of monomer, the ACM rubber was not synthesized. When the reducing agent content was smaller than five times of monomer, Rp increased while it decreased as the amount exceeded ten times. Rp increase and mooney viscosity decreased with increasing temperature.
