Abstract

Rubber networks containing unattached polymer molecules were studied previously1–5 in order to test the reptation model of de Gennes6. For a linear unattached polymer, de Gennes predicted that the time to completely renew its conformations would depend on molar mass to the third power. Experimentally the relaxation time was found to depend on molar mass to a power of 3.0 – 3.5.1,2
