Preparation Methods of Liquid Rubber

As functional polymers, low molecular weight liquid rubber has a broad application prospect in plastics processing and other fields.The methods for the preparation of monomer and rubber degradation liquid rubber were described.The monomers include free radical emulsion polymerization, free radical solution polymerization, anionic polymerization and cationic polymerization etc.; the rubber degradation methods include oxidative degradation,photocatalytic degradation, microbial degradation etc..It was pointed out that the future research direction of liquid rubber is to explore new synthetic techniques and polymerization system; by reducing production costs, improving post-treatment process and fully recovering solvents to realize environmental friendly process.
