Abstract:
A polyurethane (meth)acrylate oligomer, having a tri-block symmetric structure BAB, comprises a polyether central block A linked by two urethane bonds to respectively two terminal hydrophobic blocs B based on hydrophobic polyester oligomers having a terminal (meth)acryloyloxy alkylene group. A curable composition (1k) comprises the oligomer and may be used for soft touch coatings in electronics, consumer goods and vehicle manufacture, as the resulting cured soft touch coating.

Claim (Index 10):
A method of preparing the polyurethane oligomer according to  claim 1 , wherein it comprises the following successive steps:\n i) preparation of a mono (meth)acrylated polyester monoalcohol B\u2014OH, by a directreaction of a lactone with a hydroxyalkyl (meth)acrylate followed by the ring opening polymerization of said lactone, leading to said polyester monoalcohol B\u2014OH, reaction of two moles of said B\u2014OH monoalcohol (2 OH) with two moles of a diisocyanate OCN\u2014R\u2014NCO (4 NCO) and 1 mole of a polyether diol (2 OH) leading to said polyurethane di(meth)acrylate oligomer, with R being the residue of said diisocyanate.
