ABSTRACT:
Ultra fine polypropylene fibers having a length of 1-100 microns and a diameter of 0.05-2 microns are admixed with a polyester resin composition comprising a polyester resin of a polyhydric alcohol and an unsaturated polycarboxylic acid admixed with a solvent such as styrene in an amount effective to cause the resulting thickened composition to have a thixotropic index of 1.5-8. The resulting thickened composition is useful for building or repairing fiber glass-polyester boats. The incorporation of such ultrafine polypropylene fibers in an epoxy resin composition also thickens the epoxy resin composition and causes it to have a thixotropic index of about 1.5-8.
