Title:
POLYOL ARYLCARBNATE COMPOSITION AND POLYMER THEREFROM
Document Type and Number:
Japanese Patent JPS60124604
Kind Code:
A
Abstract:
Polyol(allyl carbonate), e.g., diethylene glycol bis (allyl carbonate), are polymerized in solution, i.e., in an organic solvent, until from 15 to 50 percent of the allylic carbon-carbon linkages are consumed. The solvent is then removed yielding a product that is gel-free, syrupy viscous liquid of unpolymerized monomer and polymer. This liquid polymer can be polymerized to a hard, transparent material with less shrinkage. Also described is the addition of mono- or polyfunctional acrylates to the liquid polymer to produce a polymerizable mixture that can be cured quickly with the addition of a free-radical initiator.
