  • Adhesives with low level of residual monomers and process for manufacturing same
    Patent number: 5990229
    Abstract: An adhesive, which contains olefinic polymers and less than 1% by weight of free monomers, is manufactured via catalytic hydrogenation. It is preferably used in the area of cosmetics, in the foods sector, in medicinal plasters and transdermal systems.
    Type: Grant
    Filed: September 12, 1997
    Date of Patent: November 23, 1999
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: Thomas Hille, Paul M. Petersen, James Burkert, Paul B. Foreman
  • Method for preparing hydrophobically-terminated polysaccharide polymers and detergent compositions comprising the polysaccharide polymers
    Patent number: 5627273
    Abstract: The present invention is directed to methods of preparing hydrophobically-terminated polysaccharide polymers. The methods utilized to prepare the hydrophobically-terminated polysaccharide polymers utilize water as the reaction solvent and do not utilize any cosolvent. The invention is also directed to hydrophobically-terminated polysaccharide polymers which are useful as deflocculants in liquid detergent compositions and to the liquid detergent compositions which contain the hydrophobically-terminated polysaccharide polymers.
    Type: Grant
    Filed: January 31, 1995
    Date of Patent: May 6, 1997
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: John S. Thomaides, James Burkert
  • Polymerizable saccharide monomers which contain a single, polymerizable, .alpha.-methyl styryl moiety
    Patent number: 5563252
    Abstract: Polymerizable, saccharide-derived monomers are prepared in processes which utilize water as the reaction solvent and which preferably do not utilize a cosolvent. The saccharide monomers are prepared from a saccharide unit, an amine selected from the group consisting of R.sup.3 NH.sub.2, where R.sup.3 is selected from the group consisting of a C.sub.1 -C.sub.18 alkyl group, H or NH.sub.2, and a single, polymerizable, .alpha.-methyl styryl moiety. The saccharide monomers are useful in preparing polymers for use in freeze-thaw stable aqueous-based compositions which do not require conventional freeze-thaw solvents and colorimetrically detectable polymers which are used in treating aqueous systems.
