Abstract: Compositions of acrylic polymers comprising: A) from 70% to 99.5% by weight of a thermoplastic resin based on homopolymers or copolymers formed by monomers containing only one double bond polymerizable by radical route, of which at least 20% by weight are (meth)acrylic monomers, B) from 0.5% to 30% by weight of a preferably crosslinked elastomer having an on-set glass transition temperature (Tg) lower than 0° C., in said composition the component B) being dispersed in the resin A) under the form of spherical and/or elongated particles having a diameter in the range of about 10 nm-2,000 nm, the particles of component B) optionally including particles of component A).

Abstract: Use of monovalent salts of saturated and unsaturated fatty acids C.sub.10 -C.sub.18 as external lubricants in granules formulation based on acrylic polymers for injection molding at temperatures from 180.degree. C.-220.degree. C. of articles having a thickness greater than 10 mm, preferably the lubricant amount is from 10 to 100 ppm; and related compositions.

Abstract: Coextruded multilayer sheets comprising a first outer layer consisting of a blend containing polyvinylidene fluoride having an average mollecular weight (Mw) not higher than 250,000 and an acrylic resin and at least a layer of a homo or copolymer of an alkylmethacrylate, having a Vicat degree (49N, 50.degree. C/h) of at least 90.degree. C., in mixture with 5-40% by weight of an elastomer in the grafted form.
