A large number of polypropylene samples, of isotacticities spanning the range 0.35 to 1.00 mm, have been examined by differential scanning calorimetry (DSC) in order to establish a calorimetric index for determining stereostructure. Crystallization s

8. Active Center Determination in Ziegler-Natta Polymerization: an Innovative Dual-Labeling Approach
Widely used radiotracer methods for active center determination, employing 14 CO tags and tritiated alcohol quench, generally provide conflicting results, thus casting doubt on the validity of both methods. This paper seeks to harmonize the apparent

A method is proposed for the determination of low levels of moisture in rubbers and other soluble polymers. The material for analysis is dissolved in an appropriate solvent and triethylaluminium is added to react with the water contained in the sampl

This study examines the application of infrared (IR) spectrometry to the determination of polypropylene (PP) stereoregularity. The use of the absorption bands at 998 cm−1 and 841 cm−1 as indices of isotacticity and bands at 1167 cm−1 and 973 cm
