ABS resin is a two-phase complex structure of amorphous thermoplastic excellent overall performance , is widely used in the automotive industry, electronics , electrical appliances , textiles , appliances and building materials . This experiment was to improve the performance of the ABS resin , the following research : emulsion polymerization of synthetic rubber content of 70% of the ABS powder , a gel content of 70 ? S- powder and a gel content of 60% of the ABS powder with SAN the resin was prepared by blending a rubber content of 10 % , 20 % , 30 % , 40 % , 50? S resin, investigated the ABS powder rubber particle size , rubber content, and the influence of the phase morphology of the mechanical properties of the ABS resin ; emulsion polymerization synthesis SAN resins and ABS powder blend , research SAN matrix relative molecular weight of ABS resin properties impact; high temperature continuous bulk polymerization method , with toluene as solvent , TDDM as a molecular weight modifier , respectively, to four functional groups the initiator JWEB50 and monofunctional initiator tert-butyl peroxide as an initiator to synthesize T-SAN , and the M-SAN resin and ABS powder blend with 60 % gel prepared with different gel content of the T-ABS and the M-ABS resin investigated SAN structure the impact on the performance of an ABS resin ; experimental results show that : ( 1) 60 % and 70% of the rubber content of the ABS resin powder with SAN resin prepared by blending an ABS resin , when the rubber content of the ABS resin is less than 30 % 70% of the ABS resin prepared by the rubber powder has a high impact strength , tensile properties were lower than the gel content 60 in all blend composition under conditions ? ABS resin prepared by the S- powder ; (2) ABS resin relative molecular weight of the SAN resin of the matrix phase is the higher , the better the mechanical properties of the obtained ABS resin , when the molecular weight of more than 400,000 , the matrix phase is SAN resin molecular weight of the molecular weight of the ABS resin . (3) T-ABS resin compared M-ABS resin impact strength was increased by about 17%, tensile strength of nearly identical ; PB rubber particles dispersed in M-SAN in the T - SAN than the more uniform, and the particle diameter is more homogeneous , fracture whitish area rubber particle shape change significantly ; T - ABS resin having better heat resistance than the M-ABS resin .
