Abstract: Abstract: a series of poly Methylmethacrylate-Butadiene-Styrene (MBS) resin were synthesized by seeded emulsion polymerization techniques, methylmethacrylate-styrene -acrylonitrile (MSAN) resin was synthesized by suspension polymerization. Matrix polymer of transparent Acrylonitrile-Butadiene-Styrene (ABS) resin were blend of polymethylmethacrylate (PMMA) resin and poly Acrylonitrile-styrene(SAN) resin or methylmethacrylate-styrene-acry- lonitrile(MSAN) resin.TransparentAcrylonitrile-Butadiene-Styrene (ABS) resin was prepared by blending these MBS resins with matrix polymer. Influence of different composions of PMMA/SAN-T on properties of transparent ABS resin were research and the effect of MSAN matrix on property of transparent ABS resin was also studied. It is found that when matrix polymer was PMMA/SAN resin, impact strength and transmittance of transparent Acrylonitrile-Butadiene- Styrene (ABS) resin increase first, and then decrease；Haze of ABS decrease first, and then increase with the increase of content of PMMA in matrix polymer.Transparent ABS resin,with MSAN as matrix, has better mechanical properties but worse optical properties.
