An equation giving the gel fraction of polymers undergoing simultaneous crosslinking and
scission is derived for an arbitrary initial molecular‐size distribution. Application is made to …

A statistical calculation of the gel point and of the molecular size distribution is made for
cross‐linked high polymers of arbitrary initial size distribution. The weight‐average …

Computer calculations of the fraction of gel as a function of radiation dose have enabled
tables to be constructed of the relation between gel fraction and number of crosslinks for …

In long-chain polymers an insoluble network or gel may be produced when a number of the
separate molecules are linked together. A theoretical derivation is given of the relationship …

The kinetics of polymer growth and especially gelation are discussed for a system of
reacting J-functional monomeric units. The gelation models of Flory and Stockmayer are …

The conditions are examined under which the fracture of main-chain bonds in a long-chain
polymer, which would normally result in a decrease in average molecular weight, can …

The gelation of polymerizing systems containing multifunctional reactants has been shown
by Floryl to be due to the sudden formation of macroscopic network molecules. For …

Flory's method for the calculation ofextent of reaction at gelation of polymer systems is
extended in an approximate manner to include ring formation. In some cases the formulas …

A general equation is derived for the critical conversion at the gel point in free radical
crosslinking polymerizations by omitting the equal reactivity assumption from the …

Results The following quantities are presented in Table I: the dilutions, D, ie, the ratio of
volume of polymerizing solution to volume of final polymer; the extents of reactions at …
