摘要： THE MELT FLOW OF THERMOPLASTIC POLYNARYLENE SULFIDE) RESINS CAN BE DECREASED BY HEATING AT A TEMPERATURE BELOW THE MELTING POINT OF THE POLYMER IN THE PRESENCE OF CERTAIN MELT FLOW MODIFIERS, E.G., SULFUR. AROMATIC SULFIDE POLYMERS TREATED IN ACCORDANCE WITH THE INVENTION RETAIN THEIR THERMOPLASTIC NATURE AND CAN BE USED IN A VARIETY OF INDUSTRIAL APPLICATIONS, E.G., AS MOLDING COMPOSITIONS.

摘要： MOLDABLE COMPOSITIONS WHICH ARE SUITABLE FOR FORMING INTO VARIOUS FINISHED PRODUCTS ARE PREPARED BY ADDING UP TO 50 WEIGHT PERCENT BASED ON THE TOTAL WEIGHT OF THE COMPOSITION OF A HYDRAULIC CEMENT TO A POLY(ARYLENE SULFIDE) RESIN. IN A PREFERRED METHOD OF PREPARING THE MOLDABLE COMPOSITIONS A SLURRY OF A POLY(ARYLENE SULFIDE) RESIN AND A HYDRAULIC CEMENT ARE FORMED, THE LIQUID IS ALLOWED TO EVAPORATE, AND THE RESULTING GRANULAR MIXTURE IS HEATED, CURED AND THEN SUBJECTED TO MOLDING, YIELDING MOLDED ARTICLES HAVING GOOD VALUES IN MODULUS, TENSILE AND IMPACT.
