A method of coating a polymer, wherein the polymer is treated with an activator to produce a reactive polymer, eg having at least one X (halogen) group and at least one H A method comprising the step of treating the polymer with a base to desorb HX. The reactive polymer is reacted with a reactive coating, such as PVP, preferably in the presence of an initiator such as persulfate anion to produce a coating polymer that appears to be essentially hydrophilic. To do. |
