Urethane di(meth)acrylate derivatives of 1,3-bis(1-isocyanato-1-methylethyl)benzene |
摘要 |
Urethane di(meth)acrylate derivatives (I) of 1,3-bis(1-isocyanato-1-methylethyl)benzene are new. Urethane di(meth)acrylate derivatives of 1,3-bis(1-isocyanato-1-methylethyl)benzene of formula (I) are new. R = H or linear 1-8 C alkyl; X, Y = a group of formula (IIA), (IIB) or (IIC); R<1>, R<6> = (un)substituted 6-12 C aryl, 7-16 C alkylaryl or 7-12 C arylalkyl; R<2> = H, 1-5 C alkyl or (un)substituted 6-12 C aryl; R<3>, R<5> = H or methyl; R<4> = 1-8 C alkylene, optionally with oxygen (-O-) atom(s) in the chain, or phenylene; T = carbonyl (-CO-) or a chemical bond; W = -O-, sulfur (-S-) or imino (-NR<7>-); R<7> = H or linear 1-6 C alkyl; R<3> not = methyl if R = H and R<4> = dimethylene. Independent claims are also included for compositions containing (I); and the preparation of (I). |
