  • Process for making silicone particles
    Patent number: 4962165
    Abstract: An improved process for manufacturing silicone-containing polymer particles is provided. The process is particularly useful for preparing uniform, crosslinked silicone rubber particles of controlled particle size distribution and submicron size. In another embodiment, the process can be used to modify the surface properties of silicone-containing polymers to improve their compatibility with and dispersion into other polymers.
    Type: Grant

  • Imide polymers
    Patent number: 4954574
    Abstract: Glutarimide polymers having an acid and anhydride content lower than the acid and/or anhydride content normally present in the glutarimide polymers. Blends of the reduced acid and anhydride glutarimide polymers with thermoplastic materials are disclosed. A process for altering the properties of imide polymers by reducing or substantially removing acid and anhydride levels normally present in the imide polymer is also disclosed.
