Manufacturing method for molded multilayer article

Resin compositions for laminated sheets and laminated sheets produced therefrom are disclosed, the compositions comprising at least one allyl ester resin composed of a polybasic acid and a polyhydric alcohol, wherein an allyl ester group of said resin is bonded to at least one of terminals thereof.

Allyl ester resin composition and laminated sheet using the same

A laminate is disclosed, comprising substrates which are impregnated with a curable composition, laminated and cured, wherein the curable composition comprises (i) a curable prepolymer having a main chain consisting essentially of a random copolymer of a vinyl monomer and an acrylic or methacrylic monomer, and a side chain containing an acryloyl or methacryloyl group at the terminal, as a main component, and (ii) a crosslinkable vinyl monomer.

Fibrous substrates impregnated with a curable composition

A propylene polymer composition comprising (A) a modified propylene polymer obtained by treating: (1) 100 parts by weight of a propylene polymer or a mixture of a propylene homopolymer and a ethylene-propylene copolymer rubber, with (2) 0.1 to 50 parts by weight of an organic compound having at least one unsaturated bond in the molecule and a hydroxyl group and (3) 0.01 to 20 parts by weight of an organic peroxide; and (B) a propylene polymer, wherein content of the component (A) in the composition is 5 to 50% by weight. This composition may further contain one or more of (C) an amorphous ethylene-propylene copolymer having a propylene content of 20% to 50% by weight and a Mooney viscosity ML.sub.1+4 at 100.degree. C. of 20 to 100, (D) a high-density ethylene copolymer having a density of 0.935 g/cm.sup.3 or more, (E) a linear low-density ethylene copolymer having a density of not less than 0.900 g/cm.sup.3 but less than 0.935 g/cm.sup.2, a melting point of 106.degree. C. to 130 C., a melt flow rate of 0.01 to 100 g/10 min. and substantially having 3 to 35, based on 1,000 carbon atoms of the backbone carbon chain, of the side-chain alkyl groups having 1 to 10 carbon atoms, and (F) an inorganic filler. The resultant composition has not only an excellent adhesion to polyurethane without the use of a primer, but also has a good weathering resistance.
