The invention aims to provide a resin primer which can stick an insulator layer to a conductor foil whereof the surface is not much roughened with sufficient adhesive force, a conductor foil with resin, a laminated sheet and a method of manufacturing same. The resin primer of the invention comprises a resin having film-forming ability and a breaking energy of 0.15 J or more. The conductor foil with resin of the invention comprises a resin layer comprising a conductor foil and the aforesaid resin primer. Further, the laminated sheet of the invention comprises the conductor foil, an insulating layer disposed facing the conductor foil, and a resin layer comprising the aforesaid resin primer disposed between the conductor foil and insulating layer so that it is in contact therewith. This laminated sheet can be manufactured by heating and pressurizing a laminate comprising the aforesaid conductor foil with resin, and a prepreg laminated on this resin layer.
A process for the bulk polymerization, in the absence of any solvent, of a reactant containing azide functionality and a reactant containing a terminal alkyne functionality, in the presence of Cu (I) catalyst or in the presence of a Cu(II) catalyst without a reducing agent, is described. Polymerization can be achieved at temperatures less than 100° C., which is suitable for low temperature cures. A controlled synthesis for low molecular weight oligomers is disclosed.

Melt-fusible polyimides based on pyromellitic dianhydride and at least one defined aromatic diamine are useful in making low-void composites and thermoplastic tapes, which can be fabricated into articles such as, for example, aircraft and autobody panels, printed circuit boards, etc. Some of these polyimides are melt-processible and can be fabricated by conventional procedures such as extrusion and injection molding.

Es werden Polyimide mit wiederkehrenden Einheiten der allgemeinen Formel I
beschrieben, worin
A der Rest einer Verbindung mit mindestens einem aromatischen Sechsring ist, wobei jede der vier Carbonylgruppen an ein anderes aromatisches Kohlenstoffatom von A gebunden ist und wobei jeweils zwei Carbonylgruppen an benachbarten Kohlenstoffatomen stehen, und
B der Rest einer Verbindung mit mindestens einem aromatischen Sechsring und mindestens einer Hydroxygruppe ist,
und ggf. bis zu 80 mol-% Einheiten entsprechender Struktur, in denen statt B ein Rest D mit mindestens einem aromatischen Sechsring, aber ohne Hydroxygruppen enthalten ist. Die Polyimide sind als alkalilösliche Bindemittel für hochtemperaturbeständige Photoresists und zur Herstellung von Schutz- und Planarisierungsschichten in der Photoresisttechnik geeignet.
