Polymer Structures - Molecular Weight

3 important questions on Polymer Structures - Molecular Weight

How do you obtain the number-average molecular weight Mn?

By dividing the chains into a series of size ranges and then determining the number fraction of chains within each size range.

What is the degree of polymerization (DP)?

The average number of repeat units in a chain.

How is DP related to Mn?

DP = Mn / m
