A group of high molecular weight fluorinated and non-fluorinated graft stabilisers were synthesised by thermal ring-opening esterification of anhydride copolymers. Methyl vinyl ether-maleic anhydride copolymers and maleic anhydride-octadecene copolymers were reacted with alcohols and were characterised using NMR, FTIR, and thermal analysis. Their phase behaviour in supercritical carbon dioxide, vinylidene fluoride was also studied. The effect of stabiliser architecture on the molecular weight and morphology of the PVDF polymer product was investigated. GPC and SEM were used to characterise molecular weight and morphology of PVDF polymers. 30 refs.
