| Abstract: |
Ternary copolymerisations of tri-n-butyltin acrylate (TBTA) or tri-n-butyltin methacrylate (TBTMA) with itaconic acid (IA) or dimethylitaconate (DMI) and N-vinyl-2- pyrrolidone (NVP) were carried out in solution at 70 C in the presence of a free radical initiator. Experimental, terpolymerisation data agreed with calculations based on the Alfrey- Goldfinger equation. Ternary azeotropic compositions for TBTA-IA-NVP and TBTA-DMI-NVP systems were 52.60: 14.80: 32.60 and 56.60: 26.60: 16.80 mol%, respectively. Also ' ... |
