Cured polyester plastic compositions derived from recycled polyurethanes |
| abstract |
Cured, thermoset plastic articles derived from scrap polyurethanes are disclosed. The polyurethane is converted to a liquified mixture containing digested polyurethane and cyclic, unsaturated anhydride. A Lewis acid then catalyzes insertion of the cyclic, unsaturated anhydride into the polyether backbone of the polyurethane to give a liquid, unsaturated resin. The unsaturated resin can cured with a vinyl monomer in the presence of a free-radical initiator to give a cured, thermoset plastic. |
