How Compounding Can Affect the Polymer Properties?
As stated earlier, EB processing requires no special compounding to modify a polymer. However additives can be used to modify the efficiency of cross-linking. For instance, scission-yield of polymers undergoing EB irradiation can be reduced through blending with polyfunctional monomers such as trimethylol propane triacrylate and other multifunctional unsaturated acrylates13. Such compounds promote the cross-linking reaction through radiation induced rapid free radical induced propagation reactions and aid in formation of a three-dimensional network structure via grafting through their double bonds. They also act as plasticizers providing efficient contact between chains. This result in the enhancement of such properties as the mechanical strength of the EB treated polymer. Polycyclic aromatic compounds such as naphthalene and anthracene are known as ‘antirads’ because they offer radiation protection, since they scavenge energy by easily forming excited states. Antirads can be used to c
