  • Patent number: 5391435
    Abstract: A polymeric material used in laminates with metal comprises an interpenetrating polymer network composed of a cyclic moiety-containing pollyallyl compound optionally with an aromatic difunctional compound (co)polymerized and cross-linked in the presence of a free radical initiator, and an epoxy resin cross-linked with a polyhydric phenol.
    Type: Grant

  • Patent number: 5110867
    Abstract: Polymeric materials comprising an interpenetrating network (IPN) prepared from allyl polymers and epoxy resins. The allyl polymers are crosslinked under the influence of a radical initiator, the epoxy resin is crosslinked by a curing agent. The curing agent is a cyclic anhydride containing a polymerizable double bond. The two networks are interlinked as a result of the double bond being involved in the curing reaction of the allyl polymers. The cyclic anhydride preferably is maleic anhydride. Preferred IPN's are prepared form triallylcyanurate or triallylisocyanurate-based allyl polymers and phenol-type epoxy resin.

  • Patent number: 4882226
    Abstract: A carrier material usable as such in chromatographic separations or as a starting material which, upon linkage to it of compounds containing ionic groups, ligands or bio-active materials can be used as ion exchanger, as a clinical selective adsorbent, as a medium in affinity chromatography or in enzymatic reactions and consists of a core material obtained by addition polymerization of monomers of which at least 50 mole % consists of (meth)acrylic acid or an ester forming equivalent thereof and a hydrophilic coating material, which is covalently bonded to the core by complete or partial conversion of the carboxyl function with a compound containing at least three carbon atoms and an epoxy group, the epoxy groups that are still present having been converted by etherification and/or hydrolysis to form an ester of a compound containing a hydroxyl group or an oligomer thereof having a molecular weight not higher than 1000, as well as a process for preparing the same.
