  • Patent number: 9676924
    Abstract: A method of making a benzyl cis-cyclohexane 1,2-dicarboxylate triester having the steps: a. forming a reaction mixture by reacting the following three components: i. a synthetic or biobased reagent selected from the group consisting of an alpha-hydroxyester and a beta-hydroxyester, ii. an anhydride selected from the group consisting of cis-hexahydrophthalic anhydride, 4-methylcyclohexane-1,2-dicarboxylic anhydride, and 3-methylcyclohexane-1,2-dicarboxylic anhydride, and iii. an alkylamine catalyst; and b. contacting benzyl chloride with the reaction mixture to yield a product that is free of phthalates and includes at least one benzyl cis-cyclohexane 1,2-dicarboxylate triester.

  • Patent number: 9441103
    Abstract: A composition includes an first anhydride-grafted polyethylene; and a cross-linking agent that includes a second anhydride; and a first material including minoxidil, melatonin; pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate); or a (2,2,6,6-tetramethylpiperidin-1-yl)oxyl derivative, where the composition is a master batch configured to cross-link a silane-grafted polyethylene material; and the composition is tin-free.

  • Patent number: 6893588
    Abstract: A method of manufacturing a container for containing an oxygen sensitive products from a heated plastic by blow molding the plastic with a compressed gas that is inert to the oxygen sensitive product. The heated plastic may contain an oxygen barrier layer or an oxygen scavenging component. The gas is also inert to the oxygen scavenging component, if it is present. An exemplary compressed gas is nitrogen gas. The blow molding may be extrusion blow molding, injection blow molding or stretch blow molding. The plastic may be, for example, a polyolefin, a nylon, or a polyester.
