Abstract

The modification of poly(vinyl chloride) was carried out with iminodiacetic acid (IDA, C4H7NO4) and iminodiacetic acid dimethylester (IDADM, C6H11NO4), as well as with n-dodecanethiol (DT, C12H26S) in the presence of K2CO3. The reaction was carried out at different temperatures below 100 °C with dimethyl formamide (DMF) and cyclohexanone as solvents. IDA did not show any reactivity, probably due to the dipolar character of the molecule. IDADM caused the elimination of HCl, while only substitution ratios of about 3 % were observed. However, the modification of PVC with DT resulted in a substitution rate of 18 % without elimination. DT-PVC showed excellent thermal properties, comparable with those of the unmodified polymer.
