专利号:US-5225492-A 优先权日:1992-02-13 标题:Living carbocationic polymerization of poly(isobutylene-β-methyl vinyl ether) 发明人:KENNEDY JOSEPH F; PERNECKER TIBOR; IVAN BELA 权利人:UNIV AKRON 摘要:The synthesis of poly(isobutylene-b-methyl vinyl ether) (PIB-b-PMeVE) by living carbocationic polymerization (LC(+)Pzn) employing the sequential monomer addition (SMA) technique is described. The process starts by producing the living PIB(+) block employing the 2-chloro-2,4,4-trimethylpentane (TMPC11/TiCl4 initiating system in the presence of the common ion salt tetra-n-butylammonium chloride (n-Bu4NCl) in CH3Cl/n-C6H14 or CH2Cl2/n-C6H14 mixed solvents at -80 DEG C. and continues by the addition of methyl vinyl ether (MeVE). The second living block forms only in the presence of excess TiCl4 suggesting that the species that starts the second block and subsequently sustains its growth is a MeVExTiCl4 complex. The stoichiometry of this complex (1:1 or 1:2) is uncertain. The TiCl4 remains attached to the MeVE units after their incorporation into the diblock, however, it can be readily removed by water. PMeVE obtained in the presence of excess TiCl4 degrades by dealcoholation, however, degradation is prevented by the use of n-Bu4NCl. Various length (composition) diblocks have been prepared and characterized. The novel PIB-b-PmeVE's exhibit strongly amphiphilic character.
