  • Cross-linkable compositions based on polyphenylene ethers and unsaturated monomers copolymerizable radically
    Patent number: 5171761
    Abstract: Toughenable polymer compositions cross-linkable thermally or by the effect of U.V. radiation are composed of:1) A polyphenylene ether (PPE) deriving from the (co)polymerization of one or more substituted phenols by oxidative coupling;2) At least one mono-unsaturated monomer compound able to (co)polymerize in the presence of radical initiators;3) Optionally, at least one polyunsaturated monomer compound able to (co)polymerize in the presence of radical initiators;4) At least one radical polymerization initiator;5) Possibly at least one (co)polymer with elastomeric characteristics;6) Usual additives, stabilizers, accelerators and flame retardant agents.Finished articles essentially composed of an intimately copenetrated polymer blend are obtained by thermal treatment or U.V. radiation of these compositions contained in suitable moulds either along or in combination with other reinforcement materials.
