Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an ion-exchanger, preferably a weakly acidic ion-exchanger, having a homogeneous network structure, on the basis of an unsaturated aliphatic nitrile and in the presence of a film-forming protective colloid. SOLUTION: In this manufacturing method, (a) an unsaturated aliphatic nitrile polymerizes with a divinyl or polyvinyl ether acting as a crosslinking agent and then polymerizes with the initiator in a suspension to produce polymer beads not in a seed feeding process but in the presence of a protective colloid, and (b) the beads are functionalized into ion exchangers.

Abstract: Vulcanizable, mercaptan- and/or xanthogen-disulfide- regulated polychloroprene rubber are produced by emulsion polymerization of chloroprene and, based on polymerizable monomer used, 0 to 30 parts by weight ethylenically unsat- urated, other monomers copolymerizable with chloroprene in an alkaline medium by a process in which (1) 0.1 to 10 parts by weight of a tricyclic diterpene carboxylic acid containing at least two conjugated C=C double bonds per molecule, based on the polymerizable monomer used, and optionally (2) 0.1 to 5 parts by weight, based on polymerizable monomer used, fatty acid esters are used for their production. The polychloroprene produced in accordance with the invention may be used for the production of vulcanized rubber articles. The polychloroprene rubbers produced by the process according to the invention have a minimal tendency to foul metal molds. The pollution of wastewaters by the process according to the invention is minimal. The well-known favorable properties of polychloroprene remain unaffected.

Abstract: The polymer compounds according to the invention, comprising special amidines, mercapto compounds and elastomers, are mainly suitable for the production of thermally stable, halogen-containing vulcanised rubbers. The vulcanised, halogen-containing rubbers obtained by means of the polymer compounds are distinguished by a reduced tendency to undergo unwanted subsequent vulcanisation and are stable towards thermal and oxidative degradation at high storage temperatures.

Abstract: Production of an ion exchanger comprises: (a) polymerizing an unsaturated aliphatic nitrile with a di- or polyvinyl ether crosslinker in suspension in the presence of an initiator and a protective colloid by a method other than a seed/feed method; and (b) functionalizing the resulting polymer beads. Independent claims are also included for; (1) Polymer beads produced by step (a); (2) Use of the polymer beads as adsorption resins; and (3) Ion exchangers produced by steps (a) and (b).
