Acrylate and Methacrylate Based Copolymers

Barrall and co-workers [55] have described a Py-GC procedure for the analysis of PE-ethyl acrylate and PE-vinyl acetate copolymers and physical mixtures thereof. The pyrolysis chromatogram of PE-vinyl acetate contains two principal peaks. The first 

The pyrolysis chromatogram of polyethylene-ethyl acrylate at 475 C shows one principal peak due to ethanol. No variation in peak areas is noted in the temperature range 300-480 °C. Table 1.4 shows the analysis of 0.05 g samples of polyethylene-ethyl acrylate and polyethylene-vinyl acetate obtained at a pyrolysis temperature of 475 °C. 

Wang and co-workers [27] developed a technique involving solvent trapping of pyrolysates followed by GC or liquid chromatography for the identification of 2-10% of acrylic acid and methacrylic acids in emulsion polymers.
