Abstract
Crosslinkable, functional polymers of vinylpyrrolidone and aminoalkyl acrylamides are provided herein. Such polymers are readily crosslinked with a crosslinking agent, e.g. a multi-aldehyde, such as a di-, tri- or tetra- aldehyde, preferably, glutaric dialdehyde, to form an aqueous gel of predetermined viscosity suitable for making hydrogels, adhesives and coatings.
Claims2
A crosslinkable, functional polymer which is obtained by polymerizing vinylpyrrolidone and N-(3-aminopropyl)methacrylamide.
A crosslinkable, functional polymer which is obtained by polymerizing about 90-99.7% by weight of vinylpyrrolidone and about 0.3-10% by weight of N-(3-aminopropyl)methacrylamide.
