Abstract
It was considered as contamination, the carbonyl growing in the primary and secondary polyolefins blends and as effects of contamination, the degradation rate increasing, the induction period and the service life diminishing of the products molded from these blends. Using the carbonyl time variation during the first life, it is possible to estimate, for a given contamination, the degradation rate, the induction period and the product service life molded from polyolefins post consumers goods and so the optimal solution for the polyolefins mechanical recycling. Keywords: Mechanical recycling, secondary polyolefins, mathematical model, contamination
