Product 1

HCID 21863578Urethane acrylate

Procedure

In the same manner as in Preparation Example 1 <PUA-1>, except that 2490 g (3 mol) of polycaprolactonediol (PLACCEL208, manufactured by DAICEL CHEMICAL INDUSTRIES, LTD.) having a molecular weight of 830 as the polymer polyol, 402 g (3 mol) of dimethylolpropionic acid as the dihydroxyl compound having a carboxyl group, 1554 g (7 mol) of isophorone diisocyanate as the polyisocyanate and 238 g (2.05 mol) of 2-hydroxyethyl acrylate as the (meth)acrylate having a hydroxyl group were respectively used, a urethane acrylate was synthesized.
