It has been established that the degree of biodegradation of composites based on polyvinyl chloride and natural polymers by microscopic fungi changes as a function of the chitosan and starch content in the composites. Biodegradation of polymeric material is accompanied with change in its physicochemical properties. A number of physical factors result in an increase in the degree of biodegradation of the materials investigated.

The results of investigating the synthesis of ABS plastic in the presence of maleic anhydride are set out. It was shown that increase in the modifier content in the range 0.5–1.75 wt% leads to a reduction in the melt flow index and gel-fraction swelling index and to an increase in the glass transition temperature of the polymer.

Nanocomposites based on polyepoxy isocyanurate crosslinked systems of different chemical composition were produced in order to investigate the specific effect of technical nanocarbon on each individual polymer network. Monodispersed carbon particles were produced by methane chlorination conducted in a continuous reactor in a non-equilibrium regime with a chlorine deficit. The dependences of the forced elasticity limit, stress relaxation, etc., on the degree of filling were analysed. The possibility of interphase interaction between a specific polyepoxy isocyanurate network and ‘nanofiller’ was investigated. It was shown that a fairly low concentration (1 wt%) of monodispersed carbon particles of 20–25 nm size leads to a 25–30% increase in the elastic modulus and forced elasticity limit; similarly, the relaxation characteristics are also increased. It was established that improvement in a number of such properties is connected with the greater influence of interphase interactions between the polymer and filler on account of the large surface layer area.

The flow and heat exchange in the process of impregnation of filler by non-Newtonian fluid during the moulding of composite articles in closed moulds are investigated. Flow is described by the modified Brinkman equation. From the rheological point of view, the medium comprises a power-law fluid. In writing the energy equation, a single-temperature model is used. Dissipative heat generation is taken into account. The problem is solved by the numerical finite difference method. The effect of dissipation (the Brinkman number) on the distribution of the mass-average temperature over the length of the cavity with different Péclet numbers is shown.
