According to a process for preparing compounds having the structure (I), in which R represents C1-4alkyl, n is between 1 and 20 and X is a halogen, C1-4alkyl methacrylate is transesterified with a haloalkanol having the structure HO (CH2) nX, in which n and X have the same meaning as in structure (I), in the presence of a tetraC1-4 alkoxide titanium or dialkyltin oxide catalyst, as well as a stabilizer. |
