摘要：This invention relates to a procedure for the controlled production or for the modification of polymeric products using IR-ATR spectroscopy, wherein the case of a polymerization reaction the extinction is determined of the characteristic IR absorption bands for the monomer used and the resulting polymeric product or in the case of a polymer modification the characteristic IR absorption bands of the starting material used and of the modified polymeric product are determined, the degree of conversion or the degree of modification is calculated from the absorption bands, and when the desired degree of conversion or the desired degree of modification is reached the reaction is stopped by suitable measures. By means of the procedure, which is described according to the invention, it is possible to carry out polymerization reactions or the modification of polymeric products to the desired degree of conversion or degree of modification by means of IR-ATR spectroscopy, without high technical expenditure and under accurately controlled conditions.
