I am synthesizing a coupling agent which is used for wood polymer composite. I been able to graft the maleic anhydride on to isotactic PP using di-cumyl peroxide as a reaction initiator. Further I want to determine the molecular weight of the MAPP through viscometric method.

Polymer Hanbook is a great resource for everything regarding polymer properties. PP should be soluble in hot toluene, but you would have to use an extremely low MW PP approx. 10,000. You might have success dissolving high molecular weight PP in aliphatic, cycloaliphatic and aromatic hydrocarbons(above 80) e.g decalin, but these are pretty toxic solvents so you have to be very careful.

PP soluble in o-xylene at 140 C by using oil bath and it takes 60-80 mint
