Has typical core-shell structure in submicroscopic morphology, wherein the core is a rubber phase spherical core with the diameter of 10-100nm, and the outer part is a shell layer consisting of styrene and methyl methacrylate. Because the solubility parameters of methyl methacrylate and PVC/PC are similar, it can act as interface adhesive between PVC/PC resin and rubber particles, and can form homogeneous phase in the course of mixing with PVC/PC resin. The rubber phase is distributed in a PVC/PC continuous medium in a particle state and presents a sea-island structure, and the special structure endows the product with excellent impact performance. When 5-10% MBS resin is added into PVC/PC, the impact strength of the product can be increased by 4-15 times, and the cold resistance and processing fluidity of the product can be improved.
The existing MBS resin has long flow in the manufacturing process, wastes time, has low extraction purity and contains more impurities in manufactured products.
