  • Method and apparatus for the production of high tenacity polyolefin sheet
    Patent number: 8137601
    Abstract: A process for the production of virtually full density polyolefin suitable for further processing by drawing to form a high tenacity, highly oriented polyolefin sheet comprising: a) feeding a metered amount of polyolefin powder into the nip between two heated calender rolls; b) rolling the powder through the nip under these conditions until a coherent sheet of polyolefin is produced. According to a highly preferred embodiment, initially, the nip is set at a gap smaller than the size of the smallest polyolefin powder particle and at a temperature above the melting point of the powder and once a coherent sheet of polyolefin exits the nip the temperature in the nip is lowered to a temperature below the melting point of the polyolefin powder and the gap increased to a desired level above the thickness of the largest powder particle.

  • Process for manufacture of blocked mercaptosilane coupling agents
    Patent number: 8097743
    Abstract: Blocked mercaptosilanes can be manufactured by reacting mercaptosilanes with organic or inorganic halides or anhydrides in the presence of an acid acceptor and washing the resulting reaction product with water/brine to yield two immiscible phases: an organic phase containing blocked mercaptosilane product and an aqueous phase containing the salt of the acid acceptor. Recycle of the acid acceptor is achieved by adding base to the aqueous phase. The process is suitable to be run in either batch or continuous mode. The blocked mercaptosilane compounds are used as coupling agents in rubber mixtures.
