✦ Synopsis

E. coli and Staphylococcus aureus are used to study the antimicrobial activity of chitosan of different molecular weights (MW). The effect of the concentration and MW of chitosan were investigated, respectively, and the antimicrobial mechanism was discussed. For chitosan with MW below 300 kDa, the antimicrobial effect on S. aureus was strengthened as the MW increased. In contrast, the effect on E. coli was weakened.

Blends of small percentage of plastic grade polypropylene with fiber grade polypropylene are studied in unoriented and oriented states. A 3% blend sample has a higher spherulitic growth rate, and improved mechanical behavior in drawn fiber state as compared to the parent sample. These changes are re

## Abstract The intrinsic viscosity of a polymer A (referred to as guest polymer) in a solvent containing a second polymer B (referred to as host polymer) at constant concentration was found to be lower than the intrinsic viscosity of the same polymer in the pure solvent. This decrease becomes more
