    摘要: The present invention relates to polymer compositions (C) for the preparation of porous article, notably microporous membranes or hollow fibers. More particularly, the present invention relates to a process of preparing a porous article from a blend of at least one semi-crystalline or amorphous polymer (P) with an additive followed by a step of shaping the article and contacting the article with water to dissolve the additive and create an interconnected pore network within the shaped article.

    摘要: Described herein are polymer compositions (PC) including a polyamide (PA) and a poly(arylene sulfide) (PASP). The polyamide (PA) is a semi-aromatic polyamide derived from the polycondensation of an aliphatic diamine, a bis(aminoalkyl)cyclohexane, terephthalic acid, and, optionally, a cyclohexanedicarboxylic acid. It was surprisingly discovered that semi-aromatic polyamides derived from the cycloaliphatic diamine bis(aminoalkyl)cyclohexane or the specific combination of the cycloaliphatic diamine bis(aminoalkyl)cyclohexane and the cycloaliphatic dicarboxylic acid cyclohexanedicarboxylic acid provided for polymer compositions (PC) having improved retention of mechanical properties (e.g. tensile modulus and tensile strength) after aging in aqueous polyol solutions. It was also surprisingly discovered that incorporation of a nucleating agent in the polymer composition (PC) provided for significantly improved tensile strength retention after aging. The polymer compositions (PC) can be desirably incorporated into articles that are exposed to elevated temperatures and are designed to convey or store polyol based fluids including, but not limited to, engine coolant.
