On the scattering by polymers and copolymers at high angles

In this paper we discuss the interpretation of the large angle scattering for chains, either being rod like, rigid or presenting excluded volume effect. It is shown that on highly branched polymers one can obtain a parameter which depends on the functionality of the crosslinks and on the average length of the blocks in the chain. One shows also how this type of analysis allows the interpretation of neutron results during transesterification.
