More Information
Summary:A curable composition comprising: (A) at least one spiro-orthoester compound having at least one spiro-orthoester group represented by the formula: [I] [I] wherein n is an integer of 3-5, (B) at least one curing agent selected from the group consisting of organic polybasic acids and their anhydrides, (C) optionally, an epoxy compound having at least one epoxy group, and (D) optionally a cationic polymerization catalyst when the composition comprises ingredient (C). Said composition is small in shrinkage on curing, and provides a cured product of high dimensional accuracy when used as a molding material.
