Patent ID: 7638595

Claim:
A method for compatibilizing polymer components in commingled plastic waste recyclates, said recyclates comprising at least 30 wt. % of polyolefins, in order to form a tough thermoplastic material, said method comprising the steps of: admixing said commingled plastic waste recyclates with a compatibilization system comprised of 2-15 wt. % of an ethylene--propylene copolymer (i) or a styrene--butadiene block copolymer (ii) or a combination of an ethylene--propylene copolymer (i) and a styrene--butadiene copolymer (ii) in any weight ratio together, with 0.1-2.5 wt. % N,N′-diaryl-1 4-phenylenediamine or N-alkyl-N′-aryl-1 4-phenylenediamine or reaction product of diphenylamine and acetone or their mixture (iii) to create an admixture; and melt processing said admixture.
