Abstract: Means for the sustained release of an active agent into the environment comprise an elastomeric matrix and the active agent contained in the matrix. The matrix material has a modulus between about 10.sup.4 Pa and about 10.sup.8 Pa at 23.degree. C., and a glass transition temperature less than 0.degree. C. The matrix comprises polyurethane formed by reacting polyol and isocyanate, and the active agent can be any biologically or nonbiologically active agent that is compatible with the matrix, e.g., the insecticide 2,2' dichlorovinyl dimethyl phosphate. The inventive sustained release system has particularly advantageous release properties, e.g., it typically can release more than 70% of the active agent contained in the matrix.

Abstract: The present invention provides a non-foamed flame-retardant article of polymeric composition comprising at least 20% by weight of a monomer mixture comprising 0-0.1% by weight o-methylstyrene 0-15% by weight m-methylstyrene and at least 85% by weight p-methylstyrene; 0-80% by weight of a different ethylenic unsaturated monomer; and a sufficient amount of flame-retardants wherein the amount of flame-retardants is substantially less than would be needed had the p-methylstyrene been replaced with styrene analogs. The flame retardancy is achieved by the addition of organophosphorus or halogenated organophosphorus flame retardants.
