(METH)ACRYLATE CONTAINING POLYFLUOROALKYL GROUP AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a (meth)acrylate containing a polyfluoroalkyl group (R<f> CH2 CH2 OCOCR=CH2 ) having an ultraviolet transmittance of >=80% at 370 nm wavelength in the form of a solution of the compound dissolved in HCFC225cb at a concentration of 10 wt.%. SOLUTION: The (meth)acrylate containing a polyfluoroalkyl group is purified with a solid adsorbent composed mainly of one or more kinds of hydroxides or oxides of elements selected from silicon, aluminum, titanium and magnesium (especially silica gel).
