## Abstract A modified Andreasen sedimentation method is described for the analysis of the DDT and carrier constituents of DDT dispersible powders. As an illustration of the use of the method, a 1% (w/v) aqueous suspension of the powder is sampled with a pipette at four different times from the co

Interfacial solid/liquid interactions play a crucial role in wetting, spreading, and adhesion processes. In the case of a flat solid surface, contact angle measurements are commonly utilized for the determination of the solid surface free energy and its components. However, if such a surface cannot
## Abstract By combining a number of theoretical relationships concerning the effect of molecular weight on melt rheology, an equation may be derived for conversion of melt indexer flow rate to βapparent molecular weight.β In spite of certain evident theoretical shortcomings of this derivation, the
