Patent number: 9988565Abstract: Water-dispersible adducted rosin esters, a process for making them, and their use in aqueous tackifier dispersions for pressure-sensitive adhesives are disclosed. Reaction of a rosin with a polyol gives a rosin ester intermediate, which is then reacted with a dienophile to produce an adducted rosin ester. The adducted rosin ester is further esterified with a polyethylene glycol having an Mw<700 to produce the water-dispersible adducted rosin ester. Esterification with the low-molecular-weight PEG imparts good water dispersibility to the adducted rosin ester while maintaining compatibility with other tackifier components. Combination of the aqueous tackifier dispersions with polymer emulsions, particularly acrylics, gives pressure-sensitive adhesives that deliver good loop tack and peel properties compared with commercial alternatives, even when the coat weight is reduced by 20%.Type: GrantFiled: June 14, 2014Date of Patent: June 5, 2018Assignee: Arizona Chemical Company, LLCInventors: Tibor Pernecker, Christopher J Holmes, Leigh E Quinlan

Publication number: 20170370899Abstract: Compositions including reclaimed asphalt may be optimized for performance that is comparable with asphalt compositions that do not contain any reclaimed asphalt. In a method to determine an optimal level of reclaimed asphalt for use with at least a rejuvenator, TSRST tests are carried out on test asphalt compositions with varying levels of reclaimed asphalt (RA) materials to obtain failure temperature and failure stress data for all compositions. The test results are compared to identify composition(s) with optimal amount of RA. The optimal asphalt composition containing the maximum amount of RA for comparable performance may have a failure temperature within±5% of the failure temperature of the reference composition, and a failure stress that may be equal to or greater than the failure stress of the reference composition.Type: ApplicationFiled: June 22, 2017Publication date: December 28, 2017Applicant: Arizona Chemical Company, LLCInventors: Laurent Porot, David Broere

Publication number: 20170283738Abstract: A process and apparatus for recovering crude tall oil are disclosed. Acidulation of a crude tall oil soap stream generates a spent acid stream that comprises lignin and entrained crude tall oil. By subjecting the spent acid stream to dissolved gas flotation, a lignin phase comprising entrained crude tall oil can be recovered and causticized, resulting in recovery of most of the crude tall oil that was present in the spent acid stream. A clarified spent acid stream is also generated, which can be treated with caustic and utilized for a soap washing process that integrates easily into the overall CTO recovery process. The apparatus comprises a crude tall oil acidulation unit, a dissolved gas flotation unit, a causticizing unit, and a soap separation unit. The inventive process marries dissolved gas flotation, a well-known water treatment process, with causticization of a recovered lignin phase, a step known from batch acidulation, to improve overall tall oil recovery from a continuous process.Type: ApplicationFiled: September 12, 2015Publication date: October 5, 2017Applicant: Arizona Chemical Company, LLCInventors: Charles Douglas Foran, Francis Edwin Swann, Robert Earl Bowles
