Abstract
Polymers having multi-functional sites and a gel comprising a solvent swollen network of cross-linked polymer(s), of which at least one polymer comprises at least one multi-functional site. A multi-functional site is a sequence of more than one functional group. A multi-functional polymer is a polymer comprising one or more multi-functional sites and/or more than one functional group.
Claims8
A polymer network comprising a block copolymer crosslinked to a polysaccharide, said block copolymer essentially comprising at least two different polymer blocks selected from poly(ethylene imine), poly(ethylene oxide), poly(propylene oxide) and poly(acrylic acid), said polysaccharide being selected from the group consisting of carboxymethyl cellulose, carboxymethyl dextran, carboxymethyl amylose, chitin, chitosan, chondroitin, dextran sulfate, heparin and heparin sulfate.
A polymer network comprising a triblock polymer of poly(ethylene imine)-poly(ethylene oxide)-poly(ethylene imine) crosslinked to a polysaccharide selected from the group consisting of carboxymethyl cellulose, carboxymethyl dextran, carboxylmethyl amylose, chitin, chitosan, chondroitin, dextran sulfate, heparin and heparin sulfate.
A polymer network comprising a pentablock polymer of poly(ethylene imine)-poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)-poly(ethylene imine) crosslinked to carboxymethyl cellulose.
