NEW MATERIAL:A (meth)acrylate compound shown by formula I (R is H or CH3; n1 and n2 are average number of mols added; n1 and n2=1-10).

EXAMPLE: A compound shown by formula II.

USE: The compound can be readily polymerized alone by heat, ultraviolet rays, electron rays or in the presence of a radical polymerization initiator or copolymerized with another unsaturated group-containing compound and useful as vehicle of various coatings and ink composition, optical material such as lens, dental material, crosslinking agent of polymer, etc. The compound has low shrinkage factor of curing, low water absorption characteristics and excellent light resistance.

PREPARATION: A compound shown by formula III is esterified with acrylic acid or methacrylic acid to give a compound shown by formula I. The compound shown by formula III is synthesized by adding -caprolactone to hydrogenated bisphenol A.
