Use of radiation-induced degradation in controlling molecular weights of polysaccharides and conductivity of polyaniline blends

Better understanding of chemistry of radiation-induced degradation is becoming of increasing importance on account of the utilization of polymeric materials in a variety of radiation environments as well as beneficial uses of degraded polymers. In this report degrading effects of radiation have been considered from the point of views of controlling the molecular weights of kappa- and iota-carrageenans and alginates on one hand and controlling the conductivity of polyaniline blends by doping via radiation induced HCl released from poly(vinyl chloride) on the other.
