Abstract
There are disclosed urethane acrylates of Formula 1: where R, Rand Reach independently represent Chydrocarbylene, preferably linear Calkylene (such as, Calkylene; e.g. hexylene); a isophorone unit and/or a tolyl unit. R, Rand Reach independently represent: a divalent moiety of (Formula 2) where X and Y independently represent Chydrocarbylene, preferably Calkylene; and k is from 0 to 30; l is from 0 to 30; and 'k+l' is from 1 to 30; and/or a divalent moiety of Formula 3 where V and W independently represent Chydrocarbylene, preferably Calkylene; and i is from 0 to 30; j is from 0 to 30; and 'i+j' is from 1 to 30; p is from 1 to 10; and r is from 1 to 10; and RRand Reach independently represent H or methyl (i.e. Rforms respectively part of an acrylate or a methacrylate group); with the provisos that at least one of R, Rand Ris a moiety of Formula 2; at least one of R, Rand Ris a moiety of Formula 3; and when Rrepresents a divalent moiety of Formula 3, the sub moiety within Formula 3, is attached directly to the amide group in Formula 1. The UAs of Formula 1 are of non crystalline and of low viscosity and are suitable for preparing polymeric flexibilizers suitable for tenting applications. A process for preparing these urethane acrylate is also described.
