Branching of the polymer according to the polymerization are effecting to the polymers nature and polymer solutions even during the numbers of branches, which are relatively small, are effected. The reactions of chain transfer to polymer and terminal double bond polymerization in free radical polymerization create branch in polymers. In this investigation the effect of different alcohols in branching of PVAC along with catalyst of AIBN is considered. For these experimental samples, we use viscometer to find out the change of weight average molecular weight with time is considered and calculation. In term of accurate consideration with usage of the model of moment, effeteness of alcohol’s samples in number and weight average branching density, paid at the same time.
