Abstract

New linear triblock copolymers consisting of a rubbery polyisobutylene (PIB) midsegment bonded both sides by glassy cyclized poly(1,3-pentadiene) (cy-PPD) blocks were synthesized by carbocationic polymerization using sequential monomer addition. First, the living polymerization of isohutylene (IB) was induced by bifunctional dicumylmethylether (DiCumOMe)/TiCl4 as initiating system in n-hexane/CH 2Cl2 (1/1 v/v) as solvent mixture at -60°C in the presence of DMSO as electron donor (ED). After the living PIB sequences had reached the desired number average molar weight (Mn) in the range of 5000 to 25 000 g mol-1, 1,3-pentadiene (PD) was added to produce the hard cy-PPD outer blocks with Mn close to 6000 g mol-1. The crude copolymers were purified by CH2Cl2 extraction at -60°C and characterized by size exclusion chromatography (s.e.c.) and nuclear magnetic resonance (n.m.r.) spectroscopy.

<EA>New linear triblock copolymers consisting of a rubbery polyisobutylene (PIB) midsegment bonded both sides by glassy cyclized poly(1,3-pentadiene) (cy-PPD) blocks were synthesized by carbocationic polymerization using sequential monomer addition. First, the living polymerization of isohutylene (IB) was induced by bifunctional dicumylmethylether (DiCumOMe)/TiCl
<sub>4</sub>
as initiating system in n-hexane/CH
<sub>2</sub>
Cl
<sub>2</sub>
(1/1 v/v) as solvent mixture at -60°C in the presence of DMSO as electron donor (ED). After the living PIB sequences had reached the desired number average molar weight (M
<sub>n</sub>
) in the range of 5000 to 25 000 g mol
<sup>-1</sup>
, 1,3-pentadiene (PD) was added to produce the hard cy-PPD outer blocks with M
<sub>n</sub>
close to 6000 g mol
<sup>-1</sup>
. The crude copolymers were purified by CH

Cl
<sub>2</sub>
extraction at -60°C and characterized by size exclusion chromatography (s.e.c.) and nuclear magnetic resonance (n.m.r.) spectroscopy.</EA>
