THE INFLUENCE OF THE POLY(VINYL CHLORIDE) ON THE CHEMICAL STABILITY OF POLYESTER COMPOSITES

The influence of the polymeric modifier – poly(vinyl chloride) on the chemical stability of polyester composites was investigated. From the results of the research, it is found that equilibrium water absorption for polyester composites is established within 7-14 days. Water absorption of unmodified polyester material is about 1,5%.
