Abstract

The pot-life of an unsaturated polyester is increased by reacting it, under non-polymerizing conditions, with an a ,b -unsaturated aldehyde of formula <FORM:0924459/IV(a)/1> where R1 is hydrogen or an aliphatic or aromatic group and R2 is hydrogen or a lower alkyl group. Reaction is performed in the presence of an acid catalyst having a dissociation constant greater than 1x10-2 (e.g. p-toluene sulphonic acid or a boron trifluoride acetic acid complex) and, preferably, also an inhibitor (e.g. hydroquinone). The preferred polyesters are those obtained by reacting (a) an unsaturated a ,b -dicarboxylic acid, e.g. maleic, fumaric, itaconic or citraconic acid, (b) a saturated glycol, e.g. ethylene-, diethylene-, triethylene-, trimethylene, a -propylene or 1:3-butylene-glycol, and, possibly, also (c) a non-polymerizable dicarboxylic acid, e.g. succinic, adipic, sebacic, azelaic, phthalic, tetrahydrophthalic, carbic or chorendic acid. The modified polyesters are copolymerized with an unsaturated monomer (e.g. styrene, methyl methacrylate, ethyl acrylate, acrylonitrile, vinyl acetate, ethylene glycol dimethacrylate, diallyl phthalate, diallyl maleate or triallyl cyanurate) in the presence of a peroxide or hydroperoxide catalyst and possibly an accelerator (e.g. cobalt naphthenate, vanadium naphthenate or vanadium butyl phosphate). In examples polyesters obtained by reacting maleic anhydride, phthalic anhydride and either ethylene glycol or propylene glycol were reacted with acrolein and subsequently copolymerized with ethyl acrylate or styrene. The polyester may be inhibited with hydroquinone.
