Answer:

Structure, properties and application in ABS resin, rubber particles are dispersed phase, dispersed in the continuous phase of SAN resin. When subjected to shock, the crosslinked rubber particles absorb and absorb this energy, so that the stress is dispersed, thereby preventing the crack development, thereby improving the tearing resistance.The purpose of graft copolymerization is to improve the compatibility and adhesion between rubber particles and resin phases. This is related to the amount of free SAN resin and the composition of SAN resin grafted on the main rubber chain. The difference of acrylonitrile content in these two resins should not be too great, otherwise the compatibility is not good, which will lead to the cracking of the rubber and resin interface.
Industrial production methods can be divided into two categories: one is the polybutadiene or styrene butadiene rubber with SAN resin by mechanical blending on the roller, or two kinds of latex blend and copolymerization; another is adding styrene and acrylonitrile in polybutadiene or styrene butadiene styrene latex with low content of monomer emulsion graft copolymerization, or with SAN resin with different proportion of mixed use.
ABS: it is a synthetic plastic of acrylonitrile, butadiene and styreneGraft copolymerization of three monomers of acrylonitrile, butadiene, and styrene, named after the first letter of their English name. It is a kind of resin with high strength, good toughness and excellent comprehensive properties. It is widely used as engineering plastics. Butadiene styrene rubber with low content of polybutadiene latex or styrene is used as main chain, and graft copolymerization of two monomers of acrylonitrile and styrene is carried out. In fact, it is often a mixture of butadiene containing graft copolymer and acrylonitrile styrene copolymer SAN (or AS). In recent years, there are two kinds of monomers, which are copolymerized with styrene and acrylonitrile, and then mixed with graft copolymerization of ABS resin in different proportions to prepare various ABS resins suitable for different uses. In the mid 1950s, industrial production began in the United states.
Because of its good oil and acid resistance, alkali, salt and chemical reagents, and good performance, and can be plated, coated with metal layer after a good gloss, light weight, low price advantages, can be used to replace certain metals. Can also be synthesized self extinguishing and heat-resistant type and many other varieties, in order to adapt to various uses.
ABS varieties in plastics.Because of its excellent comprehensive performance and wide range of uses, it is mainly used as engineering materials, and also used in household appliances.
