All about polymers
This video discusses addition and condensation polymers.
- A polymer sample contains 30%(by weight) of chains with molecular weight 10000, 30%(by weight) of the chains with molecular weight 20000, and the rest of chains with molecular weight 30000. Calculate the number average and weight average molecular weight of the sample.
