  • Patent number: 8063127
    Abstract: An antihazing agent for noncrystalline cycloolefin resins which can inhibit the hazing of the resins due to fine cracking caused by environmental change, particularly, environmental change from high temperature and humidity atmosphere to ordinary temperature and humidity atmosphere without losing the characteristics inherent in the resins to keep the transparency of the resins and inhibit the light transmittance thereof from lowering; noncrystalline cycloolefin resin compositions containing the agent; and optical elements made from the compositions. A compound component containing a metal rosinate as the main component is used as the antihazing agent for noncrystalline cycloolefin resins. It is particularly preferable that the antihazing agent further contain one or more members selected from the group consisting of alkali metal salts, alkaline earth metal salts, and Group 12 metal salts.

  • Patent number: 8013046
    Abstract: Tall oil heads may be used in lieu of, or in combination with, conventional fatty acids in the compounding and curing of vulcanizable rubber. Tall oil heads inherently contain a significant amount of neutral materials, and their incorporation into a pre-vulcanized rubber composition allows the compounder to incorporate less aromatic oil into the composition. The composition may be made by a method comprising compounding a mixture comprising a vulcanizable elastomer, a sulfur source, and Tall Oil Heads (TOH), the TOH comprising 40-75 wt % fatty acids and greater than 10 wt % neutral materials, and heating the compounded mixture to a temperature sufficient to cause substantial crosslinking of the elastomer.

  • Patent number: 7928157
    Abstract: This invention relates to a tire with a tread of a rubber composition which contains zinc rosinate within and on the surface of said rubber composition. Said zinc rosinate promotes enhanced wet traction for said tire tread by actually replacing a more conventional zinc stearate for a tire tread rubber composition. Said zinc rosinate is a product of a combination of rosin acid and zinc oxide formed in situ within said rubber composition. Said more conventional zinc stearate is a product of a combination of stearic acid and zinc oxide formed in situ within a tread rubber composition.
