Abstract

Laser light scattering (LLS), small angle x-ray scattering (SAXS) and small angle neutron scattering (SANS) are complementary techniques.¹ Together they become unmatched among the physical methods which can investigate the structure and dynamics of polymeric materials over a large range of length and time scales. The unique features of LLS are its ability to determine not only molecular weight, size and internal motions of polymers in solution or of colloids in suspension, but also the size distribution. The applications of LLS to polymer physics and colloid science have been extensive and noteworthy, especially in particle size analysis. In this lecture, three unique examples on (1) Teflon solution characterization,² (2) coil-to-globule transition³, and (3) supramolecular formation of block copolymers in selective solvents⁴ are presented.
