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.
