Abstract
A method for adding ester side groups, e.g. liquid crystalline groups, to a polymer backbone using tin chemistry. ##STR1## The method is particularly useful for adding side groups to a polymer that contains thermally sensitive groups, such as epoxy groups, as the reaction can be carried out at relatively low temperatures. Claims are to PA0 (a) a method of adding side units to a polymer; PA0 (b) a polymer containing the side units - SnBu.sub.3 ; PA0 (c) specific polymers.
