The esterification is continued to give a resin with a melting-point of at least 80 DEG  C. and acid number not greater than 30.  Preferred proportions for (b) are from 2-6 mol. per cent.  Specified diols (a) are 2,2-di-(4-beta-hydroxyethoxyphenyl) propane, 2,2-di-(4-beta-hydroxyethoxyphenyl) butane, the polyoxyethylene ether of isopropylidene diphenol in which (m+n) is 2.6 and the polyoxypropylene ether of 2-butylidene diphenol wherein (m+n) is 2.5. Specified polyhydric alcohols (c) are glycerol, pentaerythritol, sorbitol, mannitol, sorbitan and erythritol.  The rate of cure of the resins, e.g. in the presence of 4 per cent stannic chloride, increases with increase of polyhydric alcohol. In addition to being autopolymerizable, the resins are also copolymerizable with vinyl monomers in proportions, e.g., of 25-75 per cent polyester to 75-25 per cent monomer.  A copolymer may be obtained from 40 per cent by weight of styrene and 60 per cent by weight of the polyester from equivalent amounts of fumaric acid and a mixed polyol of 71 mol. per cent 2,2 - di - (4 - hydroxy - propoxy - phenyl) propane, 4 mol. per cent glycerol and 25 mol. per cent ethylene glycol.  In examples: (1) 2,2-di-(4-hydroxypropoxyphenyl) propane and fumaric acid were esterified in the presence of hydroquinone.  Pentaerythritol was added and esterification continued to give a hard light-coloured resin of melting-point 118 DEG  C.; (2) 2,2-di-(4-beta - hydroxy - ethoxy - phenyl) propane and fumaric acid were esterified, glycerol added and esterification continued to give a resin of melting-point 120 DEG  C.; (3) 2,2-di-(4-betahydroxyethoxyphenyl) propane, ethylene glycol and fumaric acid were esterified. Pentaerythritol was added and reaction continued to give a resin of melting-point 110 DEG  C.; (4) 2,2-di-(beta-hydroxy-ethoxy-phenyl) propane, propylene glycol, fumaric acid and glycerol, giving a resin of melting-point 110 DEG C.
