The aging behavior of polymers within each of these three classes was compared, and certain relationships between structure and aging behavior were found. These relationships will now be discussed with respect to each of the three classes of materials.x, 127 leavesBTDapplication/pdfIn CopyrightLD5655.V855 1979.T358Polymers -- DeteriorationThesishttp://scholar.lib.vt.edu/theses/available/etd-03302010-020018/
