The invention pertains to an adduct obtainable by condensation of a bisepoxy compound and a P-guanamine according to the formula ##STR1## wherein X is CR.sub.3 R.sub.4 --(CR.sub.1 R.sub.2).sub.n --CR.sub.5 R.sub.6 or o-phenylidene, n is 0 or 1, and R.sub.1 -R.sub.8 may be the same or different and represent H, methyl or ethyl, and the molar ratio P-guanamine: bisepoxide is 0.60 to 0.35. The adduct is used in the manufacture of synthetic materials, notably printed wiring boards (PWBs).

A process for the manufacture of a multilayer printed circuit board including the step of depositing a noble metal onto an electrically non-conducting substrate. The substrate is first coated with a layer of polyamine polymer modified by being contacted with a compound containing at least two functional groups reactive to amino groups. The coated substrate is then contacted with noble metal ions.

Process for manufacturing a printed circuit board by coating a polymeric

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.

Interpenetrating polymer network of epoxy resin, polyallyl polymer and

Polymeric material comprising an interpenetrating network of a polyol(allyl carbonate), e.g., Nouryset.RTM.200, epoxy resin. The polymeric material is prepared by polymerizing 70 to 95 parts by weight of the polyol(allyl carbonate) by radical initiation and polymerizing partially or entirely simulataneously an epoxy resin-forming mixture by acid catalysis. The epoxy resin-forming mixture comprises 10-90 wt. % of aliphatic or cycloaliphatic polyepoxide and 90-10 wt. % of a polyol/anhydride adduct having molecular weight of 500-5,000.

Interpenetrating polymer network of an aliphatic polyol(allyl carbonate)

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.
