Polypropylene (PP) is placed in a solvent at 20C below its -temperature of 28C. You
notice the PP precipitates in solution at this temperature, forming globular particles with a
radius Rgl. Assuming the globular PP particles do not interact and can be treated as
monodisperse hard spheres, what is the excluded volume of the PP "particles" (vPP)? Assume
the degree of polymerization, N=1500,=66,l=0.154nm.
