| titleOfInvention | Low cis-polybutadiene rubber as well as preparation method and application thereof |
| abstract | The invention relates to a low cis-polybutadiene rubber as well as a preparation method and application thereof. The preparation method is characterized in that in a polymerization system formed by connecting at least two polymerization reaction kettles in series, in a non-polar solvent containing a structure regulating agent, an stable single-functionality initiator is adopted to initiate the polymerization of polybutadiene and then a conventional chain-end coupling technology is combined, so as to prepare the low cis-polybutadiene rubber having high Mooney viscosity and low SV (styrene viscosity) value (5% rubber-styrene solution viscosity at 25 DEG C). The properties of the prepared low cis-polybutadiene rubber are as follows: (1) the content of the vinyl group in a monomer unit is 8-14%wt; (2) a number-average molecular weight range is 80,000-110,000; (3) the Mooney viscosity ML[1+4] at the temperature of 100 DEG C is 45-65; (4) molecular weight distribution is 1.5-1.8; and (5) the SV value is 0.04-0.059Pa.s. The low cis-polybutadiene rubber synthesized by using the method can be applied to the field of plastic modification, and is especially suitable for preparation of a high-impact high-gloss grade polystyrene (PS) resin. |
