Several sulfone-containing polycarbonates, having inherent viscosity 0.25-0.30 dL g 01 in N,N-dimethylformamide (DMF), were prepared by melt polycondensation of diphenyl carbonate (DPC) with various aromatic and aliphatic diols, in the presence of zinc acetate as transesterification catalyst. The po

✦ Synopsis
The synthesis of new porous copolymers for chromatography purposes is presented. They are formed during the suspension and emulsion polymerization of methacrylate derivatives of bisphenol-S with divinylbenzene in the presence of the pore-forming diluent. One type of the obtained copolymers contains sulfonyl functional groups in its skeleton and the second sulfonyl and more polar hydroxyl groups. Chemical and porous structures of the obtained polymeric packings were studied.

A series of new AB-type poly(etherimide)s having bisphenol-type moiety was prepared by the one-pot polyimidization using triphenylphosphite(TPP) in N-methyl-2pyrrolidone(NMP)/pyridine solution at 150°C. Complete cyclodehydration was observed in the polymerizations as well as in model reactions. Poly
New formulations of acrylic bone cement based on methyl methacrylate/1-hydroxypropyl methacrylate (MMA/HPMA) monomers were developed with the purpose of obtaining more ductile materials with reduced polymerization shrinkage. In this way, the ductility of such materials increased, but the introductio
