摘要： The present invention relates to a process and composition for the chain stopping of vinyl chloride polymerization or copolymerization in the presence of a stable free nitroxyl radical and a phenolic antioxidant. A further subject of the invention is the use of a stable free nitroxyl radical together with a phenolic antioxidant as a chain stopping mixture for the vinyl chloride polymerization or copolymerization. A further aspect of the invention is the use of higher sterically hindered nitroxyl radicals alone as chain stopping agents for the vinyl chloride polymerization.

摘要： The new bisesters of unsaturated carboxylic acids corresponding to the following formula ##STR1## may be used in curable polyester resin mixtures which may in turn be used for the production of moldings. The curable mixtures obtainable from the new bisesters of unsaturated carboxylic acids show a higher glass transition temperature than normal polyester resins and, despite a higher crosslink density, show broader-mesh crosslinking.

摘要： A chain drive for a link chain of mining conveyors or mining extraction machines, in particular for scraper chain conveyors, includes a drive shaft. The drive power or the drive torque is introduced into the link chain by chain tooth elements. The chain tooth elements are set directly in the drive shaft in seats. For that purpose, the chain tooth elements have a lower coupling portion for interlocking engagement in the seats in the drive shaft. Accordingly, a separate chain wheel is unnecessary.
