REVISED FORMULAE FOR THE SWELLING AND THE ELASTIC PROPERTIES OF RADIATION CROSS-LINKED POLYMERS
辐射交联高聚物的溶涨与弹性性能的修正关系式

Based on Charlesby's definition of the sol quantity, the parameters for the internal structure of the cross-linking polymer were calculated for the cases of the initial molecular weight distribution of Flory and of Schulz type. The sol portion should give no contributions to the swelling and the equilibrium elastic modulus of the cross-linked sample, and the free chain ends of the gel molecules should be taken into consideration. Revised formulae for the swelling and the elastic properties of cross-linked polymers are presented.
