    摘要: A copolymer of a lactone and a polycyclic carbonate is prepared by heating a monomer of a lactone with a polycyclic carbonate having two cyclic structures including a carbonate group at elevated temperatures less than 200 degrees Centigrade in the presence of a catalyst. The described copolymers evidence excellent mechanical properties, good resorption velocity and do not disintegrate upon degradation into materials of high crystallinity.

    摘要: The invention relates to a randomly branched polyamide comprising at least units derived from: 1. AB monomers, 2. at least one compound I, being a carboxylic acid (Av) having a functionality v≧2 or an amine (Bw) having a functionality w≧2, 3. at least one compound II, being a carboxylic acid (Av) having a functionality v≧3 or an amine (Bw) having a functionality w≧3, compound II being a carboxylic acid if compound I is an amine or compound II being an amine if compound I is a carboxylic acid and the amounts of all units derived from carboxylic acids and amines in the polyamide satisfying conditions as mentioned in claim 1. The composition of the randomly branched polyamide is such that it cannot form a crosslinked polyamide (and thus no gels, either), in particular during the prepolymerization, the polymerization, the post-condensation, the processing and the storage of the randomly branched polyamide, and this at a variety of ambient factors, for instance at elevated temperature and pressure. The polyamide is eminently suitable for the production of fiber and film, in particular for flat film.

    摘要: The invention relates to a polyamide fiber whose polyamide is heavily branched. The branched polyamide preferably has 3-20 branches which are joined to a core molecule which is smaller than the polyamide arms. The arms originate preferably from functional groups which are identical and are preferably carboxyl groups. The polyamide is chosen from the group of polyamides which are produced by polycondensation of .alpha.,.omega.-aminocarboxylic acids or by ring-opening polymerization of lactams. Preferably, the polyamide is nylon-6. The properties of the fiber according to the invention are at least at the same level as those of fibers obtained by spinning linear polyamide. The spinning process for the fiber according to the invention is less susceptible to faults. Inter alia, the viscosity of the polyamide no longer changes during the spinning process.
