Beschreibung
Zusammenfassung:	Monomers and monomer mixtures selected from monohydric and polyhydric alcohol esters of acrylic and methacrylic acids, acrylonitrile, vinyl chloride, styrene, mixtures of the above acrylic and methacrylic acid esters, mixtures of styrene and an unsaturated alkyd resin, mixtures of diallyl phthalate and an unsaturated alkyd resin, and mixtures of (a) monohydric alcohol esters of acrylic and methacrylic acids, and (b) an unsaturated alkyd resin, are polymerized by irradiation in a liquid state with high energy electrons at a dose accumulation rate not exceeding 1 X 106 Rontgens per second, until a solid product is obtained. The ester of acrylic or methacrylic acid may be methyl, ethyl or butyl acrylate, methyl or ethyl methacrylate, ethylene glycol or tetraethylene glycol diacrylate or dimethacrylate, dipropylene glycol or pentamethylene glycol dimethacrylate or glyceryl trimethacrylate. The unsaturated alkyd resin is preferably obtained by the use of an unsaturated acid or anhydride, such as maleic acid or anhydride, fumaric acid, itaconic acid or anhydride, or mesaconic acid. The process may be made continuous by polymerizing the monomer in bulk, solution or emulsion on a moving belt. Reference has been directed by the Comptroller to Specification 665,262.ALSO:Monomers and monomer mixtures selected from monohydric and polyhydric alcohol esters of acrylic and methacrylic acids, acrylonitrile, vinyl chloride, styrene, mixtures of the above acrylic and methacrylic acid esters, mixtures of styrene and an unsaturated alkyd resin, mixtures of diallyl phthalate and an unsaturated alkyd resin, and mixtures of (a) monohydric alcohol esters of acrylic and methacrylic acids and (b) an unsaturated alkyd resin, are polymerized by irradiation in a liquid state with high energy electrons at a dose accumulation rate not exceeding 1 x 106 roentgens per second, until a solid product is obtained.
