  • Patent number: 5977274
    Abstract: The present invention is directed to precipitation polymerization processes for the manufacture of polymers prepared from N-vinyl formamide monomer, the processes including the steps of contacting the N-vinyl formamide monomer with a polymerization medium containing t-butanol as diluent and a free-radical initiator, under conditions effective to polymerize the N-vinyl formamide monomer, thereby forming a precipitate of the polymer in the polymerization medium, substantially isolating the precipitated polymer from the polymerization medium, contacting the substantially isolated polymer with a wash containing a different diluent than the t-butanol used in the polymerization and isolating the washed polymer from the wash.

  • Patent number: 5932639
    Abstract: The present invention is directed to remoistenable and non-remoistenable adhesives which contain at least about 50 wt % of a maltodextrin syrup having a reducing sugar content of about 5-19 dextrose equivalent and solids content of about 60-80 % water, and an effective amount of other conventional adhesive additives. When the adhesive is a remoistenable adhesive, a chemically derivatized starch having an amylose content of 40 % or less and a D.S. of about 0.01 to less than about 0.50 is used. A preferred remoistenable adhesive also contains polyvinyl acetate and/or ethylene vinyl acetate in an amount from about 15-90 wt. % The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized or underivatized granular starch, by a high solids, single phase enzyme conversion process. When derivatized, the maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50.
