Abstract
Acrylic copolymers are used in the textile industry as binders for nonwoven fabrics, pigment printing or finishing. These binders must stabilise the fabrics during treatments such as washing and dry cleaning. For this purpose self-crosslinking acrylic copolymers or mixtures of acrylic copolymers and amino resins are often used. In this work, a method has been developed to determine whether reactive acrylic comonomer and/or amino resin are present in the acrylic copolymers. The technique applied, based on coupled pyrolysis-gas chromatography-mass spectrometry, can be used to separate and identify all the pyrolysis products of the polymer.
