| Abstract. | Work describes effectiveness of application of nanodimensional sols of silicon for updating PVC compositions is considered. Results of research of change physical, mechanical and operational processing behavior of polyvinylchloride compositions are given at introduction of nanodimensional sols of silicon acid. It is established that introduction of 0,002-0,003 mass. parts sols of silicon in PVC composition leads to increase in durability (on the average for 12 %), to heat stability increase from 15 to 22 minutes (approximately for 47 %) and to decrease of water absorption by 55 %. Melt flow rate tends body height to 0,003 mass. parts sols of silicon in composition. For an assessment of possible chemical interaction sols of silicon with PVC method IR-spectroscopy was used. It is shown that improvement of structure and physical condition of polymeric composition can be at the expense of emergence of hydrogen bridges and streamlining of structure of water in the conditions of polar groups of PVC, and also thanks to structure-forming effect of the loose d-orbitals of silicon and the lone electronic pairs of chlorine and oxygen of the polymer, owing to bonding of donor-acceptor character. |
