Reaction Conditions

Reaction Steps

The same reactor as used in Referential Example 1 was charged with 134 parts (1 mole) of trimethylolpropane, 684 parts (6 moles) of epsilon-caprolactone and 0.04 part of tetrabutyl titanate, and the temperature of the mixture was raised to 180° C. in an atmosphere of nitrogen. The mixture was maintained at this temperature for 6 hours to give a 1:6 (by mole) trimethylolpropane/epsilon-caprolactone adduct. The temperature was then lowered to 90° C., and 936 parts of tetraethyl silicate (the equivalent ratio of tetraethyl silicate to hydroxyl groups=1.5) and 5.3 parts of tetrabutyl titanate were additionally fed, and the mixture was heated at 110° to 120° C. until the distillation of ethanol ceased (3 hours) to give a tetraethoxysilane-modified resin. This resin is designated as compound (C-2-3).
