INTRODUCTION 1. INTRODUCTION The copolymerization of ethylene with 1‚ 3-butadiene to give crystalline‚ homopolymer-free‚ high molecular weight‚ substantially linear copolymer is described. Butadiene polymerizes almost exclusively in a trans-1‚ 4 structure‚ ranging in content from zero to 50 mole-%. At relatively low content of butadiene monomeric units (≤30 mole-%) X-ray crystallinity is of polyethylene type with a slight variation of the structural parameters. At higher levels of

SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such
