    摘要: The invention relates to stabilized recycled plastics, which can be obtained from domestic, commercial and industrial waste or valuable material collections, comprising a macrocyclic compounds containing a radical of formula (I) or (II), in the macrocycle or in a side group of the macrocycle, where the macrocycle comprises at least 8 atoms and in which the substituents R, independently of one another, are methyl, ethyl or propyl, or two radicals R on the same carbon atom are, together, a pentamethylene radical, and a is the number 0, 1 or 2. The invention also relates to a process for the stabilization of recycled plastics and to the use of the above macrocyclic compounds as stabilizer. ##STR1##

    摘要: An increase in the molecular weight of a polyamide or recycled polyamide, essentially without crosslinking, can be achieved by blending said polyamide with a polyfunctional epoxy resin and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half-ester and heating the blend to above the melting point (or the glass transition temperature) of the polyamide, in the absence of a catalyst of the type used in the polymerization of polyamides.

    摘要: The present invention relates to flame retardant polymer compositions which comprise phosphinic acid salts in combination with polymer chain extension agents on the basis of epoxide structures and oxides or hydroxides of selected metals. The compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, such as polybutylene terephthalate (PBT).

    摘要: The present invention discloses a process for the preparation of a stabilized polyester that is low in the generation of aldehydes which comprises reacting one or more diacids with one or more diols in an esterification process, and/or one or more diesters with one or more diols in a transesterification process in the presence of an effective amount of a stabilizer selected from the group consisting of (a) a polyhydric alcohol which is for example poly(ethylene-co-vinyl alcohol), poly(styrene-co-allyl alcohol), maltitol, isomalt, sorbitol, xylitol, sucrose, mucic acid dibutylester, mucic acid di(phenyl-1-ethyl)ester, pentaerythritol or dipentaerythritol; (b) a compound of the formula II, which is for example di-iso-octyl-phosphinic acid; (c) a sterically hindered amine which is for example Tinuvin 123 or Tinuvin 622; (d) a polyacrylamide or a cationic acrylamide copolymer; or (e) a hydroxyamine and/or a nitrone. Such polyesters, for example PET, when extrusion compounded exhibit a lower residual acetaldehyde content than does PET alone when similarly treated. The invention pertains to any polyester used in the manufacture of bottles or containers which in turn are used to store consumer materials, especially food, pharmaceuticals, beverages and most especially water
