  • Crosslinked polymers made from 1,3,7-octatriene and like conjugated polyenes
    Patent number: 5922780
    Abstract: Polymers are made from 1,3,7-octatriene or like conjugated polyenes and a crosslinking agent having at least 2 activated double bonds such as ethylene glycol dimethacrylate. These polymers can be used to make absorbent foams that are useful in absorbent articles such as diapers, as well as latexes that are useful as binders and adhesives.
    Type: Grant
    Filed: January 10, 1995
    Date of Patent: July 13, 1999
    Assignee: The Procter & Gamble Company
    Inventors: John Collins Dyer, Bryn Hird, Pui Kwan Wong, Sharon Marie Beshouri
  • Process to prepare low density porous cross-linked polymeric materials
    Patent number: 5912276
    Abstract: Stable high internal phase water-in-oil emulsions containing polymerizable vinyl monomers, crosslinking monomers and initiators are obtained useful in producing low density porous crosslinked polymeric materials by using a surfactant system containing (a) one or more sorbitan fatty acid esters or saccharide fatty acid esters or mixtures thereof and (b) one or more quaternary salts having one or more greater than or equal to 8 carbon atom hydrocarbon groups. A water-in-oil emulsion can be formed with lower surfactant concentration than sorbitan fatty acid ester alone and improved surfactant performance at elevated temperatures is obtained. Sludge formation otherwise observed with the use of sorbitan fatty acid ester surfactants is also reduced or eliminated.
