Filed:

Dec 5, 2000

Appl. No.:

09/730085

Inventors:

Lyubov K. Gindin - Pittsburgh PA
Karen M. Henderson - Coraopolis PA
Sze-Ming Lee - Houston TX
Brian Long - Clarington OH

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

C08J 300

US Classification:

524591, 524839, 524840, 4284231

Abstract:

The present invention relates to aqueous polyurethane dispersions containing amide groups that are pendant to the backbone of the polyurethane, wherein the amide groups (calculated as NHâCOâ, MW43) are present in an amount of 1 to 14% by weight, based on the weight of the polyurethanes. The present invention also relates to aqueous, one-component, thermoset compositions containing the polyurethanes with amide groups in the backbone and a cross-linking component that is reactive with amide groups. Finally, the present invention relates to coatings, sealants and adhesives prepared from these aqueous, one-component, thermoset compositions.

Abstract:

The present invention relates to aqueous polyurethane dispersions wherein the polyurethanes contain terminal hydrazide groups and correspond to the formula wherein the terminal, modified hydrazide groups are present in an amount of 1 to 25% by weight [calculated as C(O)âNHâNHâC(O), MW 84], based on the weight of the polyurethanes, and wherein X represents ORâ or NHRâ, R represents the residue obtained by removing the isocyanate groups from an NCO prepolymer, Râ represents a group which is inert to Isocyanate groups under the conditions used to form the polyurethane of in formula I, Râ represents a divalent, linear or branched aliphatic group containing 2 to 10 carbon atoms, provided that there are at least two carbons between the oxygen atoms, wherein the aliphatic group may optionally be substituted by heteroatoms to form ether or ester groups, m is 0 or 1 and n is 2 to 4.

US Classification:

524591, 4284231, 524839, 524840

Abstract:

The present invention relates to aqueous polyurethane dispersions containing secondary amide groups in the backbone of the polyurethane, wherein the secondary amide groups (calculated as NHâCOâ, MW 43) are present in an amount of 1 to 14% by weight, based on the weight of the polyurethanes, and correspond to the formula wherein X , and X are the same or different and represent the groups obtained by removing a hydrogen atom from a hydroxy group or a primary or secondary amino group and R and R are the same or different and represent linear or branched hydrocarbon groups that are optionally substituted by groups that do not contain isocyanate-reactive hydrogen atoms. The present invention also relates to aqueous, one-component, thermoset compositions containing the polyurethanes with amide groups in the backbone and a cross-linking component that is reactive with amide groups. Finally, the present invention relates to coatings, sealants and adhesives prepared from these aqueous, one-component, thermoset compositions.
