Patent

CA 2439554

Pigmented molding compositions having good weatherability for sheet and bulk molded articles are made by mixing a resin component comprising an unsaturated polyester, a monomer which will react with the polyester and anon-aromatic, thermoplastic polymer; an ultraviolet light absorbing material and/or a hindered amine light stabilizing material; a pigment; and a reinforcing agent.

L'invention concerne des compositions pigmentées possédant une bonne résistance aux intempéries utilisées pour former des articles moulés en feuille ou en vrac par mélange d'un composant résineux constitué d'un polyester insaturé, d'un monomère qui réagit avec ledit polyester, et d'un polymère thermoplastique non aromatique; un matériau absorbant les ultraviolets et/ou un matériau de stabilisation de lumière à amine empêchée; un pigment; et un agent de renforcement.
