Problems solved by technology
The invention relates to a styrene-butadiene copolymer as well as a preparation method and applications thereof. The styrene-butadiene copolymer is obtained by regulating an arrangement mode of a polystyrene chain segment and a polybutadiene chain segment, wherein the polybutadiene chain segment can freely move. The copolymer is mainly used for preparing high-gloss and high-impact-resistance polystyrene. According to the styrene-butadiene copolymer provided by the invention, the viscosity of 5 % styrene solution of the styrene-butadiene copolymer is low, the styrene-butadiene copolymer exists in a polystyrene polymer molecular chain mainly in a block mode when being added into the polystyrene, can also freely flow in the polystyrene, can be used for improving the physical and mechanical properties of the polystyrene and is particularly used for keeping high gloss of the polystyrene when the properties are impacted.
