Aqueous dispersions of polyurethane/acrylic hybrid compositions |
| 摘要 |
An aqueous dispersion of polyurethane/acrylic polymer hybrid composites is made by forming a mixture of urethane prepolymer or polymer, acrylic monomer or polymer, ketone functional molecule/oligomers, and hydrazine functional molecule/oligomers; and dispersing the mixture so made in aqueous medium. |

1. An aqueous dispersion of urethane polymer composition comprising:
a) a urethane polymer or prepolymer having lateral chain pendant groups with ketone functional moiety(ies) wherein said lateral side chain pendant groups with ketone moiety(ies) are free of basic nitrogen groups; said ketone functional moiety(ies) selected from ketone groups, b) a molecule with two or more hydrazine functional moieties characterized by a number average molecular weight of less than 2000 Daltons, said hydrazine functional moieties and said ketone functional moiety being capable of forming azomethine linkages to crosslink said urethane polymer, and wherein said dispersion includes acrylic monomers and/or acrylic polymer. |
