  • High flow, high ductility poly(arylene sulfide) resin blends
    Patent number: 5723542
    Abstract: A poly(arylene sulfide) resin composition is provided which contains a low molecular weight poly(arylene sulfide) resin, a high molecular weight poly(arylene sulfide) resin and impact modifiers. The compositions exhibit enhanced levels of low temperature impact properties. The compositions are useful in the manufacture of molded articles. Preferably the compositions utilize an elastomeric block copolymer as the impact modifier, and further comprise an epoxy functional alpha-olefin elastomer.

  • Polymer mixture comprising polyarylene sulphide elastomeric polymer and metal salt
    Patent number: 5681893
    Abstract: The invention relates to a polymer mixture comprising A) a polyarylene sulphide, B) an elastomeric polymer having reactive groups which are capable of reacting with the polyarylene sulphide, the polymer mixture moreover comprising as constituent C) a metal salt of a fatty acid having a melting temperature lower than the compounding temperature of the polymer mixture. The presence of the metal salt C contributes to an improvement of the mechanical properties, in particular the ductility.
