Abstract: High rubber content transparent MBS was synthesized via two-step emulsion graft polymerization. The effect of molecular weight regulator. rubber partcle size and rubber content on the mechanical and optical properties of MBS and PVS/MBS was investigated. MBS mixed with rubber particles of 1 μm (from bulk-suspension process) and 0.2 μm (from emilsion process) was used to modify PVC resin with satisfactory results. The morphology of PVC/MBS blends was studied by TEM.

Key words: MBS resin, PVC resin, emulsion polymerization, toughened plastics, TEM
