| Abstract: | Physical properties-structure relationships have been investigated for polyurethane networks. Sol fraction, swelling and elastic modulus have been measured. Structural parameters derived from these measurements have been compared with those from theoretical models. As a result, the behaviour of these these networks appears to lie between those of phantom and affine network models. |
