摘要:
A method of preparing polydiorganosiloxane polyoxamide copolymers is described. These copolymers have at least one polydiorganosiloxane segment and at least two aminooxalylamino groups. The method can be used in the presence or absence of a solvent. Intermediates involved in the preparation of the copolymers are also described.
