Abstract Styrene-butadiene latex (SBR) with a particle size of 80 nm was prepared by emulsion polymerization, and acetic acid was used as agglomerating agent to agglomerate SBR to about 300 nm. The SBR-g-MS graft copolymer with 60% SBR was synthesized by grafting styrene (St) and methyl methacrylate (MMA) by seed emulsion polymerization. It was melt blended with polymethyl methacrylate (PMMA) and styrene-acrylonitrile copolymer (SAN) to prepare the transparent ABS resin. The effects of the composition and structure of the SBR-g-MS graft copolymer and the blending ratio of PMMA/SAN on the properties of the transparent ABS resin were studied. The results showed that matching the refractive index of the matrix resin and the SBR latex particles can help to obtain the ABS resin with excellent transmittance. When the mass ratio of butadiene (Bd) to styrene in SBR was 70/30, the ABS resin with m(PMMA)/m(SAN) was 44/56 had the best transmittance; when m(Bd)/m(St) was 75/25, m(PMMA)/m(SAN) was 48/52, m(Bd)/m(St) was 80/20, m(PMMA)/m(SAN) was 53/47, the ABS resin has the best transmittance, the transmittance was above 85%. Furthermore, when the ratio of grafting comonomer St to MMA was 25/75, the optical performance of ABS resin was the best and the transmittance was 86.46%. As the blending ratio of SBR-g-MS graft copolymer and matrix resin increased, the impact strength of ABS resin increased, and the transmittance dropped suddenly when the rubber content was more than 15%. When the rubber content was 15%, the impact strength of the transparent ABS resin was 158.7 J/m, and the transmittance was 86.46%.
