he formulae calculating effective crosslinking chain elements
effective elastic chains
pendant chains and their average polymerization degree have been deduced by use of the sol gel distribution theory obtained by authors in reference[7]. The experimental and theoretical results about the relation between the elastic modulus and the density of effective elastic chains of polyurethane containing HTPB are basically identical
