1. Estimate the degree of polymerization of with an average molecular weight of 150,000 the molecular weight of an ethylene monomer is 28
2. To enhance processability of a polymer why would you want to decrease its molecular weight?
3. Increasing the molecular weight of of a polymer increases its strength and stiffness, as well as its viscosity. is too high of a viscosity a limiting factor when increasing the strength by increasing the molecular weight? why?
the term vapor pressure almost always means the equilibrium vapor pressure. what pysical arrangement is needed to
