    摘要： There are disclosed urethane acrylates of Formula (1) : where R1a, R1b and R1c each independently represent C2-15hydrocarbylene, preferably linear C3-12alkylene (such as , C4-8alkylene; e.g. hexylene); a isophorone unit and/or a tolyl unit. R2a, R2b and R2c each independently represent: a divalent moiety of Formula (2) where X and Y independently represent C2-10hydrocarbylene, preferably C2-8alkylene; and k is from O to 30; I is from O to 30; and 'k + I' is from 1 to 30; and/or a divalent moiety of Formula (3) where V and W independently represent C2-10hydrocarbylene, preferably C2-8alkylene; 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 R3a R3b and R3c each independently represent H or methyl (i.e. R3 forms respectively part of an acrylate or a methacrylate group); with the provisos that at least one of R2a, R2b and R2c is a moiety of Formula (2); at least one of R2a, R2b and R2c is a moiety of Formula (3); and when R2 represents 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.
