Abstract

1425744 Methyl methacrylate polymer articles E I DU PONT DE NEMOURS & CO 2 April 1973 [3 April 1972 (2)] 15717/73 Heading C3P A filled plastic article of manufacture comprises (a) 50 to 76% by weight of a hydrate of alumina in particulate form; (b) 4 to 20% by weight of glass filaments having a length of 0À1 to 3À0 inch; and (c) 20 to 40% by weight of a polymeric constituent, at least 50% by weight of which is derived from methyl methacrylate monomer; the percentages being based on the weight of the article. The articles may be prepared by polymerizing a mixture of the monomers, hydrate and filaments in the presence of an initiator on a casting surface, e.g. part of a compression mould. In the examples syrups comprising methyl methacrylate homopolymer, methyl methacrylate, ethylene dimethacrylate, t-butyl peroxymaleic acid, calcium hydroxide, water, ethylene glycol dimercaptoacetate, alumina trihydrate, fibreglass, lauroyl peroxide, lubricant, titanium dioxide, carbon black, octanoic acid, hexanoic acid, decanoic acid and dichloroacetic acid are polymerized in moulds to form sheets.
