    摘要: A mixture consisting of a polymaleimide and a copolymerizable monomer or a prepolymer formed from these two compounds contains, as the polymerization catalyst, an ethane which is substituted by aromatic groups and hydroxyl groups or halogen (cf. formula II), such as benzpinacol. The mixture is stable on storage and heat-curable. It can be cured, while at the same time being shaped to give mouldings, sheet-like structures, laminates, adhesive bonds or foams, for example by casting or compression moulding.

    摘要: Polymerizable compositions comprise(a) a compound containing in the same molecule both at least one phenolic hydroxyl group and at least two groups chosen from allyl, methallyl, and 1-propenyl groups, e.g., 2,2-bis(3-allyl-4-hydroxyphenyl)propane or bis(3-(1-propenyl)-4-hydroxyphenyl)methane,(b) a compound containing at least two mercaptan groups per molecule, e.g., pentaerythritol tetrathioglycollate, and(c) a heat-activated crosslinking agent for phenol-aldehyde novolac resins.The compositions are caused to polymerize by the action of irradiation of free-radical catalysts. The polymers so obtained, containing more than one phenolic hydroxyl group, can be subsequently crosslinked in situ by heating. The compositions are useful in various two-stage operations, such as the production of multilayer printed circuits.Polymerizable compositions may also comprise(d) a compound as (a) but containing at least two phenolic hydroxyl groups,(e) a compound containing more than two mercaptan groups per molecule.On irradiation or on heating in the presence of a catalyst, preferably a free-radical catalyst, these compositions crosslink, they are useful as adhesives in forming coatings on polar substrates.

    摘要: The invention relates to solutions which are stable on storage and which contain curable mixtures of polymaleimides, comonomers for these polymaleimides and, optionally, polymerization catalysts and compounds which contain at least one furyl radical, preferably furfuryl alcohol. The solutions are used for the manufacture of crosslinked polymers containing imide groups. Usually a substrate is impregnated with the solution. After drying, curing is carried out at 100 to 300.degree. C. Using a known method, for example, glass fibre fabric is subjected to hot pressing together with a copper foil, curing being effected. This gives correspondingly copper-coated laminated sheets which are outstandingly suitable for the manufacture of printed circuits.
