Patent ID: 7828271

Claim:
A process for preparing an alkoxypolyoxyalkylene (meth)acrylate without isolation of intermediates comprising: initially charging at least one metal alkoxide having the formula MetOR 10 to a reactor; adding at least one alcohol having the formula R 12 OH to the reactor; pumping at least one alkylene oxide of the formula (VI) into the reactor and reacting the at least one alkylene oxide of the formula (VI) with the metal alkoxide having the formula MetOR 10 to form an intermediate reaction product; and directly adding (meth)acrylic anhydride to the reactor; and reacting the (meth)acrylic anhydride with the intermediate reaction product to obtain the alkoxypolyoxyalkylene (meth)acrylate; wherein Met is lithium, sodium, potassium, rubidium or cesium, R 110 is a linear or branched alkyl radical, the R 11 radicals are each independently hydrogen or a linear or branched alkyl radical having 1 to 8 carbon atoms, and the R 11 radicals are same or different, R 12 is a linear or branched, optionally alkoxylated alkyl radical having 1 to 18 carbon atoms, a molar mass of R 12 is less than a molar mass of the alkoxypolyoxyalkylene (meth)acrylate.
