  • Lubricant fillers in a discrete phase
    Patent number: 4246159
    Abstract: A method for incorporating a low melting lubricant filler in a polymeric matrix by mixing the lubricant filler with a monomer or polymer precursor while the filler and the monomer or precursor are in the liquid phase and subsequently polymerizing the mixture. The polymerizable mixture is prepared using nonintensive mixing to preserve the discrete phase of the lubricant filler.
