  • Publication number: 20020045681
    Abstract: The present invention provides polymeric additive systems and processes for preparing polymeric additive systems which contain a liquid component and a solid component, wherein the weight fraction of the solid component is more than 50%. The present invention also provides polymeric compositions and processes for preparing polymeric compositions that include a polymeric component and a polymeric additive system which contains a liquid component and a solid component, wherein the weight fraction of the solid component is more than 50%. The disclosed compositions and processes are useful in the preparation of polymeric materials and articles produced therefrom.

  • Publication number: 20020013387
    Abstract: The plastics additives powder compositions of the present invention are provided as powder particles having impact modifier particles and processing aid particles which are coagulated and dried. When blended in thermoplastic resins, such as PVC, the subject plastics additives powders both increase the impact strength and improve process efficiency and melt strength. The impact and processing properties achieved by the present invention are more efficient than using separate impact modifier and processing aid powders. The method of preparing the powder compositions of the present invention also enable impact modifier particles having rubber weight fractions greater than 88% to be isolated as free-flowing powders.

  • Patent number: 6271898
    Abstract: Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.
