Using as an internal standard the methylene absorbance at 1470 sm-1 and the absorbance of C-O-C groups at 900, 930, 1100 and 1240 sm-1, it was determined that the absorbance at 1100 sm-1 is available for quantitative IR analysis of copolymers of trioxane and glycidyl ethers. © 1996 Elsevier Science Ltd.enArticle
