COMPOSITION OF ACRYLIC POLYMER WITH IMPACT RESISTANCE USING EMULSION LATEX

摘要

A polymethylmethacrylate resin composition is provided to improve the dispersibility of impact reinforcing agent to a matrix resin, to show impact resistance while reducing the degradation of heat resistance and scratch resistance. A method for manufacturing a transparent polymethylmethacrylate resin composition comprises the steps of: (i) emulsifying by using an anionic emulsifier to obtain a latex impact reinforcing agent; (ii) mixing the impact reinforcing agent and an unsaturated momoner, and transferring the coagulated impact reinforcing agent by using a specific coagulant to the unsaturated monomer phase; and (iii) polymerizing the unsaturated monomer phase dispersed with the coagulated impact reinforcing agent.
