ABSTRACT

For polyolefins (PO) stabilization and protection against ageing the method is proposed
for their thermochemical modification in organosilicon liquid. The efficiency of their
chemical modification has been shown by the example of polyethylene (PE) and
polypropylene (PP) by means of phenylaminomethylmethyldietoxysilane. Stabilization
efficiency is estimated by physical-chemical methods, by the possibility of recycling
processing of PO, by the results of mechanical testing of non-modified and modified PO
at pre- and post-artificial ageing of materials. The values of short-term strength of PO
on extension, compression, bending, specific impact viscosity, fatigue strength at
bending, on relative elongation and elasticity modulus at extension are presented. The
proposal has been made that the modification of PO by organosilicon compounds offers
the good prospects from the viewpoint of utilization of industrial-domestic waste, for
reducing of demand for initial polymeric raw material and for prevention of
environmental contamination.
