  • Elastomeric thermoplastic copolyesters endowed with high rheological and mechanical properties and an improved ageing resistance
    Patent number: 5173528
    Abstract: A rheological and mechanical properties and the ageing resistance of the elastomeric thermoplastic copolyesters are remarkably improved by the addition of a synergistic mixture of a polycarbodiimide and a quinolinic antioxidant.The copolyesters containing the above synergistic mixture find use in the extrusion technology.Said copolyesters, when they are subjected to a heat treatment at a temperature lower than 150.degree. C., increase the melt viscosity so that they can be used in the blow-molding technology.

  • Process for the surface modification of synthetic fibers
    Patent number: 4510185
    Abstract: A process for obtaining water-dispersable polyolefin fibers endowed with a high degree of cohesion consists in maintaining the fibers in contact with a stable emulsion formed by a water solution of polyvinyl alcohol and a poor solvent for the polyolefin, under stirring in turbulence conditions, at a temperature lower than the boiling temperature of the emulsion.
