Abstract:
Composition consisting essentially of two essentially immiscible polymers A and B and a stable mixture of at least two polymers C and D, each of these polymers C and D being individually at least partially miscible with one of the polymers A and B,wherein the polymers A and B are selected from the group consisting of the following pairs:polyethylene (PE)/polyamide (polyethylene/polyisobutenepolypropylene (PP)/other polyolefinPP/PAPVC (polyvinyl chloride)/polyolefinABS (acrylonitrile/butadiene/styrene)/PAPC/polyesterPC/ABS whose acrylonitrile content results in immiscibilityPVDF (polyvinylidene fluoride)/polyolefin andPVDF/rubber (polyethylene/propylene),wherein the stable mixture of at least two polymers C and D is selected from the group consisting of:PVC/ABSPVC/ASA (styrene/acrylonitrile grafted onto acrylic polymer)PVC/PMMA (polymethyl methacrylate)PVC/polyurethaneABS/SMA (styrene/maleic anhydride copolymer)ABS/polyamides (Poly(2,6-dimethyl-1,4-phenylene ether) (PPE)/polystyrenePPE/PAPPE/polyolefinChlorinated polyolefin/aliphatic polyesterPolyetherimide/polyetherketone (PEK) or Polyetheretherketone (PEEK)Polysulphide or polyethersulphide/ABS, PET or PBT (polyethylene or polybutylene terephthalate) andPVDF/PMMA, andwherein the mixture of at least two polymers C and D constitutes a compatibilization system for the two essentially immiscible polymers A and B.
