Abstract: A laminated plate or film (I) comprises (1) a substrate layer containing (a) 1-99 wt.% of a graft copolymer prepared from (a1) 1-99 wt.% of a particulate graft base formed from (a11) 80-99.9 wt.% of 1-18C alkyl ester of acrylic acid, (a12) 0.01-20 wt.% of a polyfunctional cross-linking monomer, (a2) 1-99 wt.% of a graft component consisting of (a21) 40-100 wt.% styrene, optionally substituted and/or a (meth) acrylic acid ester, (a22) 0-60 wt.% acrylonitrile or methacrylonitrile whereby (a2) consists of a graft shell and (a) has an average particle size of 50-1000 nm; (b) 1-99 wt.% of a copolymer consisting of (b1) 40-100 wt.% styrene, optionally substituted and/or a (meth)acrylic acid ester, (b2) 0-60 wt.% acrylonitrile or methacrylonitrile; (c) 0-80 wt.% polycarbonate; and (d) 0-50 wt.% fibre and/or particulate filler; and (2) a transparent top layer consisting of polymethylmethacrylate. Also claimed are moulded articles prepared by thermoforming of the laminated plate (I).

Abstract: Laminated sheet or foil, comprises: (1) a substrate layer containing (a) 1-99 wt% graft copolymer with an average particle size of 50-1000 nm, comprising (a 1) 1-99 wt% particulate grafting base derived from (a 11) 80-99.99 wt% 1-8 C alkyl acrylate(s) and (a 12) 0.01-20 wt% polyfunctional crosslinking monomer(s), with (a 2) 1-99 wt% of at least one grafted shell derived from (a 21) 40-100 wt% styrene, substituted styrene and/or (meth)acrylate ester and (a 22) up to 60 wt% (meth)acrylonitrile, (b) 1-99 wt% of a copolymer of (b 1) 40-100 wt% styrene etc. (as in a 21) and (b 2) 2-60 wt% (meth)acrylonitrile, (c) 0-80 wt% polycarbonate, and (d) 0-50 wt% fibrous or particulate filler; and (3) an outer layer of polymethyl methacrylate (PMMA). Also claimed are (i) another laminated sheet or foil, and (ii) fabrication of sheet laminate and moulded products.
