ABS Polymerization Process

ABS comprises the dispersed phase of styrene/acrylonitrile copolymer grafted on polybutadiene rubber and the continuous phase of styrene/acry-lonitrile copolymer. The use of SAN grafted on polybutadiene rubber provides high impact strength, processability, chemical resistance, staining property, etc., as the characteristics peculiar to ABS resins. 

The basic property of ABS resins is impact resistance. In connection with this, various theories relating to the impact property have been established. The rubber particles disperse impact energy through efficient generation and annihilation of craze. By such crazing, the energy is annihilated with deformation of rubber particles to create the cavitation of rubber particles. This phenomenon can be confirmed through transmission electron
