Abstract

1305762 Laminated products MINNESOTA MINING & MFG CO 4 March 1970 5 March 1969] 10463/70 Heading B5N [Also in Division C3] Laminates are prepared using prepolymers containing cyanurate rings linked by -OR-O- groups and having -O-R-OCN groups which can react to give a cured resin, R being a divalent aromatic residue or a plurality of such residues linked by -O-, -CO-, -S-, -SO 2 - or a hydrocarbon group, or R is a methylene-terminated divalent fluoroaliphatic chain. In an example a prepolymer is obtained by heating 1, 3-dicyanato benzene with zinc acetylacetonate as a catalyst and used to impregnate glass cloth from which a laminate is prepared. The prepolymer may also be used to bond aluminium panels and to impregnate paper to form composites.
