“…Further progress in the development of novel types of polycondensation, of non-equilibrium matrix polycondensation in particular, has established a number of characteristic features, e.g., the effect of a heterogeneous matrix on the formation of copolymer microstructure and other properties of polymeric systems. 3, 56 ± 60 In contrast to polymerisation in the presence of fillers, which has been studied in great detail, 61,62 polycondensation and polyaddition in the presence of a dispersed solid phase were first described in the 1970's. The subjects of these studies were polysiloxanes, 63 polyurethanes 64 and epoxide oligomers.…”

“…Synthetic polymers, such as polyacrylamide, polycarbonic acids, polyhydroxyethylacrylates and others may serve as the continuous phase in composites. Besides, clayey materials initiate or inhibit numerous reactions of polymerization and indirectly influence the process changing its direction, thereby producing composition systems with modified structure and new properties [9,10].…”

Composition gels on the basis of bentonite clay of Manrak deposit (East-Kazakhstan region) and nonionogenic polymers -poly-2-hydroxyethyl-acrylate and polyacrylamide were synthesized by radical intercalative polymerization in situ with various content o f cross-linking agent N,N-methylene-bisacrylamide and with time of intercalation about 8 hours. The morphological structure, the nature of interaction of components and the swelling ability of composition gels were studied by scanner electron microscopy, equilibrium swelling and IR-spectroscopy methods. By studying of morphological structure it was determined, that the polymer-clay composition gels, synthesized by intercalative polymerization, are most homogenous and interconsistency in case of "acrylamide-clay" composition in contrast with "2-hydroxyethylacrylate -clay" composition. For "acrylamide-clay" gels the swelling degree of gels was stated to decrease with the increase in the content of cross-linking agent and ionic strength, but "2-hydroxyethylacrylate -clay" compositions have the extremely character of swelling, where maximum degree of swelling account for gel with content of cross-linking agent 1*10 -2 М. Interaction of composition components was realized on account of hydrogen bonds with formation of chemically cross-linked complex polymer-clay. Decrease of swelling degree of compositions in physiological solution points to acquisition of polyelectrolyte nature of composition gels on account of combination of nonionogenic macromolecules of polymers with negatively charged particles of bentonite clay. For intercalated samples of polymer-clay compositions, the degree of swelling at all degrees of cross-linking is between those for pure polymers and pure clay, that in turn, agrees with the conclusion on the great composition homogeneity of samples with preliminary intercalation. As of results of holding investigation fit is safe to say, that obtained polymer-clay composition gels are potential sorbents and prolongated carriers of medicines.

SYNOPSISIn this work we present a new technique to prepare polyolefin-fiber composites. This technique is based on chemical anchoring of a catalyst on reinforcing agents containing OH groups on their surface and then conducting an olefin polymerization on the supported catalyst. This technique offers the possibility to approach the challenging problems encountered in polymer composites, namely, the reinforcement-matrix adhesion, the dispersion, and the wetting of the reinforcement by the resin. As a first part of a systematic research, we report on the procedure of fixation of titanium tetrachloride on the surface of asbestos fibers and the Ziegler-Natta polymerization of ethylene on the surface-modified fibers. The procedure as well as the structure and properties of the composite were investigated by means of FTIR, atomic absorption, SEM, solvent extraction, and tensile testing. The experimental results show that the Ziegler-Natta catalyst can be efficiently anchored on the surface of the fibers to conduct successful polymerization and to "synthesize" a new class of polymer composites.
