Polymer composition (C) containing a poly(aryl ether sulfone) material (P), composed of at least one poly(aryl ether sulfone) (P1) with a multiple benzenic ring structure, or at least one poly(aryl ethel sulfone) (P1) with a multiple benzenic ring structure and at least one poly(aryl ether sulfone) (P2) different from poly(aryl ether sulfone) (P1), and a semi-aromatic polyester material (P*), composed of at least one semi-aromatic polyester (P1*) with a multiple benzenic ring structure, or at least one semi-aromatic polyester (P1*) with a multiple benzenic ring structure and at least one semi-aromatic polyester (P2*) different from semi-aromatic polyester (P1*), wherein the semi-aromatic polyester material (P*) over poly(aryl ether sulfone) material (P) weight ratio [(P*)/(P) weight ratio] is between 0.13 and 1.00.
摘要:
Use of an effective amount (ε) of a poly(biphenyl ether sulfone) (P2) for diluting a poly(aryl ether ketone) (P1) contained in a polymer composition (C1) consisting of the poly(aryl ether ketone) (P1) and, optionally in addition, one or more ingredients (A) other than the poly(aryl ether ketone) (P1) and the poly(biphenyl ether sulfone) (P2), while at least substantially maintaining the friction and/or wear resistance of the polymer composition (C1) with regard to a surface (Σ) with regard to which respectively the friction and/or wear resistance of the poly(biphenyl ether sulfone) (P2) are not as good as respectively the friction and/or wear resistance of the poly(aryl ether ketone) (P1).
摘要:
Aromatic high glass temperature sulfone polymer composition The invention relates to an aromatic high glass transition temperature polymer composition comprising: at least one aromatic sulfone polymer (P); at least one oxide of a metal; at least one carboxylate of a metal, said carboxylate comprising at least 10 carbon atoms. Preferably, the aromatic sulfone polymer (P) is chosen among the group consisting of polybiphenyldisulfone, polysulfone, polyphenylsulfone, polyethersulfone, copolymers and mixtures thereof.
