  Thermoplastic polyamideimide copolymers are provided which are excellent in both heat stability and melt viscosity characteristics at a temperature of from about 300°C to about 400°C. The copolymers of the invention comprise Units A of the formula in an amount of about 50 mole %, Units B of the formula in an amount of about 15-48 mole % and Units C of the formula in an amount of about 35-2 mole %, wherein Z is a trivalent aromatic group having two of its three carbonyl groups attached to adjacent carbon atoms, a is 0 or 1, b is 0,1,2,3 or 4, R1 is alkyl (C1-4), R2 is selected from alkyl (C1-4), halo and nitro, c is an integer from 1 to 25 and X is chosen from - SO2 -CO- or -C(CH3)2-. The copolymers may be made by reacting diamines containing the Units B and C respectively, e.g. I and II, with trimellitic acid (or another aromatic tribasic carboxylic acid with two carboxyl groups attached to adjacent carbon atoms) in an organic polar solvent using a dehydrating catalyst - or alternatively the diamines may be reacted with the acid anhydride acid chloride using a hydrochloride scavenger, subsequently closing the ring of the polyamide-amic acid thus formed.

• Process for the production of aromatic sulfide/sulfone polymers
  申请人：PHILLIPS PETROLEUM COMPANY

  公开号：EP0033906A1

  公开（公告）日：1981-08-19

  Aromatic sulfide/sulfone polymers are prepared by initially contacting a dihaloaromatic sulfone, an alkali metal sulfide, an organic amide, and, optionally, an alkali metal carboxylate under polymerization conditions and subsequently at or near completion of the polymerization reaction, adding an end-capping agent comprising additional dihaloaromatic sulfone to the reaction mixture producing a polymer exhibiting improved physical properties including melt flow stability. The resulting polymers have utility as coatings, films, molded objects, filaments, fibers, and the like.

  芳香族硫化物/砜聚合物的制备方法是：在聚合条件下，先将二卤代芳香族砜、碱金属硫化物、有机酰胺和（可选）碱金属羧酸盐接触，然后在聚合反应完成或接近完成时，向反应混合物中加入由额外的二卤代芳香族砜组成的末端封端剂，从而产生一种具有更佳物理性能（包括熔体流动稳定性）的聚合物。这种聚合物可用作涂层、薄膜、模制件、长丝、纤维等。
