Abstract

• The synthesis and the properties of block copolymers based on PPO and PC segments are reported. Copolymers that have a multi-block structure are synthesized by a polycondensation reaction that employs oligomeric PPO and PC diol terminated with phosgene or bischloroformate of bisphenol A. In the reaction scheme two steps are involved: first, the reaction of one of the oligomeric diols (PPO or PC) with the bischloroformate or phosgene; second, the oligomeric bischloroformate is reacted with the other diol. The molecular characteristics of the prepared samples are studied by SEC, 1H and 13C NMR, and FT-IR spectroscopy. The thermal and rheological properties and the thermal stability have also been investigated bymeans ofDSC, rotational rheometry, andTGA, respectively. Polymers that have a single glass transition temperature are obtained if low-molecular-weight segments are used. From a rheological point of view, thesematerials show a remarkably lower melt viscosity compared with a PPO homopolymer that has a comparable average molecular weight. (literal)
