| titleOfInvention | Styrene-isomonoolefin-styrene triblock copolymer and preparation method thereof |
| abstract | The invention relates to a styrene-isomonoolefin-styrene triblock copolymer and a preparation method thereof. The method comprises the following steps: (1) in the presence of an organic solvent and titanium tetrachloride, carrying out first cationic polymerization reaction on isomonoolefin to obtain a polymeric system containing polyisomonoolefin with reaction activities at the tail end; and (2) contacting the polymeric system with a styrene-containing solution, and carrying out second cationic polymerization reaction, wherein the first cationic polymerization reaction in the step (1) also comprises the step of introducing an initiator system, and the initiator system contains at least one compound capable of providing carbonium ions and at least one activator. The method can effectively lower the generation of the styrene homopolymer and styrene bi or high copolymer, thereby effectively enhancing the block polymerization efficiency. |
