The grafted copolymerization of 2-hydroxyethyl methacrylate to polyvinylpyrrolidone in the presence of mineral fillers (hydroxyapatite, montmorillonite and wollastonite) under ultrasound has been investigated. The effect of ultrasound, nature and amount of mineral filler on the polymerization rate and composition of copolymers has been determined. Ultrasound substantially intensifies the polymerization process and actively affects the formation of the copolymer composition. Under its action, a porous structure of composites is formed, even without adding special foaming agents. The obtained results were used to improve the technology of obtaining osteoplastic porous composites.

The regularities of compaction process of foam polystyrene plastics in the liquid mediums have been discovered. The influence of medium nature, temperature and technological characteristics of foam polystyrene (imaginary density, shredding degree) on the kinetics of gas phase release in the conditions of polystyrene segmental mobility has been determined. The design and method of calculation of the reactor for the process of foam polystyrene degazation via the continuous scheme is offered.
