Liquid crystalline (LC) block copolymers comprising polystyrene and LC polyester blocks were obtained by a three-step procedure. In a first step, hydroxyl-terminated oligoesters were obtained by polycondensation reaction of methylhydroquinone and 4,4'-dicarboxy-l,10dibenzoyloxydecane in pyridine sol
## Abstract Perfluoropolyethers are a well known and widely used family of polymers, suitable as protectives. Their main drawback is the lack of solubility, which is complete only in chlorofluorocarbons. In this work a series of AβBβA block copolymers (FluoPLA), with a relative low molecular weight
