  • Transmission lubricant
    Patent number: 9617495
    Abstract: The present invention relates to a transmission lubricant comprising at least 30% by weight of polyalkyl (meth)acrylate. The present invention further describes polyalkyl (meth)acrylates for use in lubricants and also processes for preparing them and their use. The present lubricants can be used particularly in wind turbine transmissions.

  • HEAT TRANSFER-FLUID WITH ELECTRICAL INSULATING PROPERTIES
    Publication number: 20150322322
    Abstract: The present invention relates to the use of a liquid composition as heat transfer fluid, characterized in that the liquid composition comprises polymers derived from at least an ethylenically unsaturated monomer or a mixture of ethylenically unsaturated monomers. Preferably, the liquid composition is used as a heat transfer fluid for electrical equipment.

  • POLY(METH)ACRYLATE AS MULTIFUNCTIONAL ADDITIVE IN PLASTICS
    Publication number: 20140066566
    Abstract: The present invention relates to use of a novel, single-component additive for addition to thermoplastics, in particular polyvinyl chloride (PVC). The resultant reduced friction delays melting of the thermoplastic during extrusion and therefore improves fluidity and lowers the process pressure required. The reduced friction moreover facilitates processing in shaping machinery by reducing adhesion to metal. In order to provide these technical improvements, the present invention provides a novel poly(meth)acrylate-based additive for thermoplastics, in particular for PVC. This features a poly(meth)acrylate backbone and long alkyl solid chains.
