Calculating Molecular Weight (number and weight average) for polymers
Molecular weight is an important for polymers. Since polymer processing typically produces a distribution of different chain lengths, both short and long, we need a tool that calculates the average molecular weight. We can do this based on number average or weight average. Degree of polyme
