Document Type and Number:
Japanese Patent JPS63147470
Kind Code:
A
Abstract:
Disclosed is a new urethane polyacrylate having at least one terminal isocyanato acrylic pendent radical. Preferably the molecular chain within the acrylate caps has been extended with a polyhydroxy compound just before final end capping with isocyanato acrylic. The isocyanato acrylic is preferably isocyanato ethyl methacrylate and the urethane is diisocyanate capped polyether and the polyether radical is oxyalkylene. The method for producing the urethane polyacrylate involves end capping a polyol with diisocyanate yielding a reaction product with two reactive equivalents of isocyanate and then capping less than all of the isocyanate with a hydroxyacrylate, after which the remaining isocyanate is reacted with polyol to provide chain extension. The chain extending polyol is then capped with a isocyanato acrylic. Also disclosed is a new impression material for application to mammalian tissue and curing in contact therewith; the impression material including a free radical polymerizable resin, alkyl benzensulfonyl titanate, polymerization initiator, and filler; and a method of use.
