Abstract
A novel methacrylate-based composition is disclosed. The composition is preferably used as an adhesive. The composition comprises an acrylate-based or methacrylate-based ester monomer, a catalyst, a chlorinated or chlorosulfonated polyethylene polymer resin and a graft co-polymer resin. The chlorinated polyethylene polymer resin used includes organic sulfonyl chloride. The composition preferably further includes an acrylate-based or methacrylate-based acid monomer, and a catalyst activator. A preferred chlorosulfonated polyethylene polymer resin contains about 43 weight percent chlorine, about 1.1 weight percent sulfur, and about 34 millimoles sulfonyl chloride moiety per 100 grams thereof. Preferred graft co-polymer resins are ABS, MBS, MABS, ASA, all-acrylic, SA EPDM and MAS. More-preferred graft co-polymer resins are MABS, ASA, all-acrylic and MBS. Most-preferred graft co-polymer resins are MABS and ASA. A preferred methacrylate-based acid monomer is methacrylic acid. Preferred methacrylate-based ester monomers are methyl methacrylate, ethyl methacrylate, butyl methacrylate, cyclohexyl methacrylate, 2-ethylhexyl methacrylate and tetrahydrofurfuryl methacrylate. More-preferred me…
