Abstract: Disclosed is a novel urethane acrylate being a reaction product of a raw material composition comprising at least (A) a diol component, (B) a component having acrylic unsaturation and (C) an isocyanate component. Said component (A) comprises at least one alkoxylated 2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-dialkanol, component (B) comprises at least one hydroxyalkyl acrylate, hydroxyalkyl methacrylate and/or hydroxyalkyl methylacrylate, and/or comprises acrylic acid, methacrylic acid and/or a methylacrylic acid and/or a corresponding alkyl ester of a said acrylic acid, and said component (C) comprises at least one di or polyisocyanate or a derivative thereof.

Abstract: Disclosed is a process for obtaining an acrylic compound having a tertaoxaspiro backbone and at least one acrylic unsaturation. Said compound is in embodiments an acrylate, a methacrylate or a crotonate of an alkoxylated, such as an ethoxylated, a propoxylated and/or a butoxylated 2,4,8,10-tetraoxaspiro[5.5]undecane3,9-dialkanol.
