This paper gives the names of the Russian manufacturers of low-density polyethylene, the processes they use and the capacity levels achieved. IR-and NMR-spectroscopy, gelpermeation chromatography and differential scanning calorimetry are used to make a comparison of the structure and properties of the polymers manufactured using a range of processes, based on the standard product grades. Some general inadequacies in respect of the range of products manufactured and their relation to modern market requirements are noted.
