Consider a randomly branched polymer in a dilute solution. let us assume that the radius of gyration for this polymer in an ideal state (in the absence of excluded volume interactions) is r0 = bn1/4 where b is the kuhn monomer size and tv is the number of kuhn monomers. use a flory theory to determine the size r of this randomly branched polymer in a good solvent with excluded volume y. what is the size r of a randomly branched polymer with n= 1000, b = 3 a, v = 21.6 a3 ? compare this size to the size of a linear chain with the same degree of polymerization in the same good solvent and in ฮธ-solvent.
