PRODUCTION OF HIGHLY REACTIVE LOW MOLECULAR WEIGHT PIB OLIGOMERS |
摘要 |
In one preferred embodiment, the present invention provides a process for the liquid phase polymerization of isobutylene to manufacture highly reactive PIB oligomers having Mn under 1000, using a catalyst composition comprising a Friedel-Crafts catalyst a complexing agent, a chain transfer agent and a polymerization-retarding agent. A chain transfer agent may be selected from: a-DIB and ß-DIB and mixtures thereof. 2,4,4-trimethylpent- 1 -ene 2,4,4-trimethylpent-2-ene (a-DIB) (ß-DIB) A polymerization- retarding agent may be selected from: 2,6-bis( 1, 1-dimethyIethyl )-4-methyIphenol ( B H T or 2,6-di-teri-butyl-4-vinylphenol |
