The nonuniformity is described by ratios of averages of molecular weights of the graft (co)polymers. The general feature of the nonuniformity of graft (co)polymers is that, with increasing degree of grafting and degree of polymerization of the backbone, the nonuniformity of a graft (co)polymer passes through a maximum and approaches more or less closely the nonuniformity of the backbone (co)polymer. The nonuniformities of graft (co)polymer are independent of the type of the degree of-polymerization distribution. The nonuniformity depends markedly on the disparity in the molecular weights of monomer units of the backbone copolymer and the grafts if the graft copolymer has a small number of grafts per backbone.
