Open the CIPO recordAbstract From the Canadian patent
Organic dispersions which can be cured with little shrinkage and are based on unsaturated polyester, copolymerisable vinyl or vinilydene compounds, thermoplastic polymers which are colloidally soluble and are incompatible with the polyester resin and an ethylene/vinyl acetate copolymer with high vinyl acetate contents show a good stability and thus are useful for providing cured mouldings of constant quality.
