Melt flow index values and molecular weight distributions of commercial thermoplastics
TL;DR: In this article, the melting index (MI) values from a series of polystyrene, polypropylene, linear low-density polyethylenes (butene and octene copolymers) were measured and related to molecular weight distributions of these materials, and a simple relationship between 1/MI versus Mxw (where x = 3.4-3.7) was followed for the linear polymers with similar polydispersities.

TL;DR: In this article, a stent is positioned on an undersized mandrel and the stent was coated with an excess of a polymer and drug solution, rotated to spin off the excess of the coating.

Characterization of linear low density polyethylene by temperature rising elution fractionation and by differential scanning calorimetry
TL;DR: In this paper, the branching distribution of polyethylene has been characterized by analytical Tthis paper and by DSC techniques, provided that the DSC samples are prepared at very slow cooling rates.

The use of latex rubber-modified polystyrene as a model system for HIPS : effect of particle size
TL;DR: The effect of particle size in high-impact polystyrene (HIPS) is difficult to determine because of a size polydispersity and changes in particle morphology during the HIPS synthesis process as discussed by the authors.

Supermicron poly(butyl acrylate)/polystyrene core‐shell latexes
TL;DR: In this paper, the use of an oil-soluble initiator (2,2′ azodiisobutyronitrile [AIBN]) provides a means by which large (6 μm diameter) polybutyl acrylate latex particles can be made by sequential core-shell polymerizations.
