Abstract
(EN)
Xylylene dicarbamate contains impurities represented by formulas (1) to (4) below at a ratio of less than 100 ppm as a total amount thereof on a mass basis. (In the above-described formulas (1) to (4), R represents a monovalent hydrocarbon group.)

(FR)
Le dicarbamate de xylène contient des impuretés représentées par les formules (1) à (4) dans un rapport tel que le total de celles-ci constitue moins de 100 ppm sur une base massique. (Dans les formules (1) à (4), R représente un groupe hydrocarboné monovalent.)
