| Abstract: | As the simplest nonlinear polymers,star-shaped copolymers have become a research hotspot due to their unique structure,good properties and wide applications.The synthetic approaches,methods and applications of star-shaped copolymers were reviewed.Synthesis reactions of star-shaped copolymers include anionic polymerization mechanism,atom transfer radical polymerization,ring opening polymerization,self-assembled method and coupling reaction.The 3 to 7 G star-shaped copolymers have a low toxicity in human body.The star-shaped copolymer of polylactide can be used as the controlling agent for drug release.The star-shaped copolymer added into other polymers can improve their thermal stability,toughness and dyeing.When the rate of polar group in star-shaped copolymer is 4,the inhibiting paraffin effect reaches 40.5%.The 3.0 G star-shaped PAMAM polyether demulsifier shows good demulsification performance with the dehydration rate reaching 92% for crude oil emulsion. |
