| 摘要 |
Bisphenol-A/terephthalate/carbonate copolymer substrate in direct adhesive contact with a coating layer of polymerized allyl diglycol carbonate, ("ADGC") without substantial penetration of the copolymeric substrate by the coating layer. The coated article is prepared by forming a layer of monomeric ADGC on the substrate, then polymerizing the ADGC by free-radical initiation at temperatures maintained below successively higher limits as the polymerization progresses, whereby to avoid substantial penetration of the substrate by ADGC or its polymers. The resulting article, such as a clear sheet or plate, is abrasion resistant.
