Abstract

Unsaturated polyester resins to which thermotropic polymers have been added may be cured with a smaller quantity of copolymerizable monomer for a given viscosity of the unsaturated polyester and are useful for the production of moulded parts and grouting and filling compositions which have wide applications in the building industry, the electrical industry, boat building, medical technology and the motor vehicle industry.
