Water-Tree Resistance of Ethylene-Styrene Copolymers

Synthesis and Saxs Characterization of Sulfonated Styrene-ethylene/propylene-styrene Triblock Copolymers

Block Copolymers of Styrene, Isoprene, and Ethylene Synthesis and Characterization Oxide Prepared by Anionic Polymerization. I

Anionic polymerization has been used as a technique for the synthesis of five-block copolymers of polystyrene (PS), polyisoprene (PI), and poly(ethy1ene oxide) (PEO). Two types of such polymers, PEO-PI-PS-PI-PEO and PEO-PS-PI-PS-PEO with varying PEO block length, have been prepared, using potassium naphthalene as the initiator and tetrahydrofuran as the solvent. The polymers were purified by ex...

Configurational characteristics of ethylene- vinyl chloride copolymers

Rotational isomeric state theory has been used to calculate mean-square unperturbed dimensions (r2>0 and dipole moments (/~> of ethylene-vinyl chloride copolymers as a function of chemical composition, chemical sequence distribution, and stereochemical composition of the vinyl chloride sequences. As was previously found for several other copolymeric chains, (/z2> is much more sensitive to chemi...
