A thermosetting adhesive resin suitable for binding lignocellulosic materials to form products, such as plywood or particle board, is prepared by heating an aqueous sugar or starch solution in the presence of an inorganic acid or its ammonium salt and a metal ion catalyst to obtain a partially polymerized resin which is reacted with an organic acid anhydride just prior to application to the lignocellulosis materials. The adhesive formula contains no formaldehyde and the preferred aqueous solutions are whey or whey byproduct concentrates.

A modified polyether polyol for use in the manufacture of polyurethane polymer having improved fire-resisting qualities, and the method for making such a polyether polyol. The modified polyether polyol includes a polyether polyol having urea chemically bound thereto. The method for making the modified polyether polyol includes reacting a reducing sugar with propylene oxide to produce a polyether polyol, which is then reacted with unsubstituted urea to chemically bind the urea thereto to produce a modified polyether polyol.

Enzymes and macromolecules are immobilized in vivo or in vitro on human tissue or erythrocytes by the reaction of the enzyme with a coupling agent to form an enzyme derivative containing electrophilic groups and reacting the enzyme derivative with the tissue or erythrocyte containing a sulfhydryl group or other nucleophilic group.
