  • Publication number: 20230303825
    Abstract: The disclosure relates to processes for producing lightweight polyethylene terephthalate articles such as bottles that retain good batTier properties against the permeation of oxygen, carbon dioxide and/or water vapor. The use of relatively small amounts of polytrimethylene furandicm·boxylate during the formation of the PET bottles can produce a bottle having the required barrier properties and result in the use of less material.

  • Patent number: 10011727
    Abstract: This invention provides methods and technology related to increased hiding power of a coating through mediating the interaction of the pigment with other system components including but not limited to other pigment particles, latex paint particles, latex binding particles, and organic or inorganic hollow particles. Organization and spacing are tailored via pH sensitive functionalities hosted on ligands or polymeric spacers that are located at/within the surface of one of the components.
