VERFAHREN ZUR HERSTELLUNG VON POLYISOBUTYLEN MIT ALLYL-ENDGRUPPEN.
摘要
The invention relates to a method of preparing allyl-terminated polyisobutylene (PIB) by allylation with allyltrimethylsilane of tertiary chloro-capped PIB by electrophilic substitution. The synthesis begins with the BCl3 catalyzed mono- or oligo-tertiary chloride "inifer" initiated polymerization of isobutylene, followed in the same reaction vessel by the addition of hexane, allyltrimethylsilane and TiCl4.
