This paper deals with in situ compatibilization of PE/PS blends via Friedel–Crafts reaction, performed at the interphase. Two polyethylenes having different molecular weights, and the same PS, were used along a wide range of catalyst concentration. The influence of the graft copolymer architecture and content on the efficiency of blend compatibilization was studied. The emulsifying effect, morphological...
The effect of the in situ compatibilization on the mechanical properties of PP/PS blends was investigated. The application of Friedel–Crafts alkylation reaction to the PP/PS-blend compatibilization was assessed. Styrene/AlCl 3 was used as catalyst system. The graft copolymer (PP-g-PS) formed at the interphase showed relatively high emulsifying strength. Scission reactions, occurring in parallel...
Blending of different thermoplastic polymers usually results in segregated and low value materials for almost any mixing condition. Nevertheless, a synergetic combination of properties can be obtained by an adequate compatibilization via reactive blending. In this work a Friedel–Crafts alkylation reaction is used to graft polyethylene chains onto polystyrene. The relation between the initial PE molecular...
After synthesis, poly(seleno-p-arylene diamine)s were doped with chlorine. The polymers were studied before and after doping by X-ray photoelectron spectroscopy (X.p.s.), electron spin resonance (e.s.r.) and conductivity measurements. It is suggested that chain ends may be partly terminated by groups containing oxygen. After doping, there is charge transfer complex formation as shown by X.p.s. analysis...
