Using the methods of viscometry, SEM, DMA the effect of polyetherimide (PEI) on the properties of ED-20 epoxy oligomer during and after curing was studied. It was shown that the introduction of the modifier significantly affects the kinetics of curin

Graft copolymers of poly(methyl methacrylate) and polyamide-6 (PMMA-g–PA6) were investigated via in situ anionic polymerization of e-caprolactam, using PMMA precursors with N-carbamated caprolactam pendants (PMMA–CCL) as macroactivators and sodiu

2-Acrylamidosulphamethoxazole (ASM) was synthesized and characterized by elemental analyses, IR and 1H NMR spectra. Proton-monomeric ligand dissociation and metal-monomeric ligand stability constants of ASM with some metal ions were determined potent

As-polymerized poly(L-lactide), (PLLA), has a much higher impact strength than after compression moulding. Several routes have been explored to further increase the impact strength of nascent PLLA. First results on the preparation of composites with

Networks were prepared from Poly-(Dimethyl-Siloxane), PDMS, and Poly-(Methyl-Phenyl-Siloxane), PMPS, precursor chains by telechelic condensation. The precursor was of a very low polydispersity. The functionality of the crosslinks was four.

A new procedure for the preparation of model polymer networks having an inhomogeneous distribution of crosslinks has been developed. Emulsion polymerized polystyrene/divinylbenzene microspheres, of uniform particle size, are swollen with styrene mono

Polycarbonates containing different amounts of thermolabile azo functions have been synthesized. The resulting polymeric initiators have been used to start the polymerization of methyl methacrylate. The kinetic results are explained on the basis of a
