Abstract
There are provided poly(vinyl alcohol) polymers and copolymers containing vinyl alcohol or vinyl acetate and derivatives thereof such as poly(ethylene glycol)-grafted poly(vinyl alcohol) polymers or polyether-grafted poly(vinyl alcohol) polymers. These polymers can contain various functional groups. Such polymers can be use as polymer matrix or solid support for various chemical substrates such as organic substrates and reagents. Cross-linked poly(vinyl alcohol) polymers and copolymers are also provided. Methods for preparing such polymers as well as several of their uses are also included.
