Abstract

PURPOSE:To make it possible to simply and accurately analyze a composition comprising a copolymer of acrylic ester and methacrylic ester, by performing correction by using the peak areal ratio of the monomer and the dimer of acrylic ester formed by thermal decomposition. CONSTITUTION:In analyzing the compositional ratio of a copolymer of acrylic ester and methacrylic ester by thermal decomposition gas chromatography, the ratio of monomer/dimer of acrylic ester formed by thermal decomposition is calculated by multiplying the peak areal ratio of an acrylic ester monomer and a methacrylic ester monomer formed by thermal decomposition by correction coefficient calculated from a preset correction curve. The correction coefficient is calculated from the drawing obtained by using a specimen of which the compositional ratio is known. In the next step, the compositional ratio is calculated by operation shown by formula. By this method, accurate measurement is enabled regardless of the chain length of an ester group.

For example, there is a method in which the thermal decomposition production rate of acrylic esters and methacrylic esters in a sample is determined, and this is multiplied by a certain value to analyze the composition. , a method is known in which the peak area ratio of the thermal decomposition product rate Zimmer is determined using a known sample and a calibration curve is created.

Page, 1976), but it is not easy to determine the thermal decomposition product rate, and it is necessary to carefully consider the value to be multiplied by the homopolymer mixture and copolymer. For copolymers of and methacrylic acid esters, multiplying by a certain value has the disadvantage that analysis accuracy deteriorates. On the other hand, the latter method has the disadvantage that a calibration curve cannot be easily created by experiment, and analysis is difficult in the case of a sample made by multi-component copolymerization of acrylic acid ester and methacrylic acid ester.
