W. Pyckhouthintzen et al., SANS INVESTIGATIONS OF TOPOLOGICAL CONSTRAINTS AND MICROSCOPIC DEFORMATION IN POLYMER NETWORKS, Physica. B, Condensed matter, 234, 1997, pp. 236-239
The microscopic deformation of network chains in cross-linked rubbers
under strain is addressed by small angle neutron scattering (SANS) on
labelled paths in a network. The experimental results sustain the cont
ribution of tube constraints to the rubber elasticity in networks.
