<p>90 to 99,99% mole of at least one ethylenic monomer and 10 to 0,01% mole of at least one polymerizable ultra-violet light-stabilizing acrylic ester are copolymerized at -40 DEG to 300 DEG C. and 1 to 3,000 atmospheres in the presence of a catalyst. Specified ethylenic monomers are ethylene, propylene, styrene, vinylidene chloride vinyl acetate, vinyl chloride, vinyl fluoride, acrylonitrile and butyl acrylate, while specified stabilizing esters include 2-hydroxy-4- methacryloxy-acetophenone methacryloxy benzophenone, -acryloxyacetophenone or -acryloxybenzophenone, methyl 2-hydroxy-4-methacryloxybenzoate, (o-methacryloxybenzoyl) methane and (o-acryloxybenzoyl), stearyl methane. Specified catalysts include benzoyl peroxide, di-t-butyl peroxide, dimethyl dioxide organic hydroperoxide, azo compounds and coordination catalysts. Solvents such as hydrocarbons and halogenated hydrocarbons are preferably present.</p> |
