1H and 13C NMR spectra and 1H spin–lattice relaxation times T1 and T1ρ have been employed to study the structure and molecular dynamics in polyethylene and ethylene-1-butene copolymer in the temperature range
The terpolymer could be considered a combination of a propylene-ethylene copolymer and a propylene-1-butene copolymer in analyzing the molecular chain microstructure of the terpolymer. The investigation concluded that with increase of elution temperature, ethylene and 1-butene content of the polymer ...
Ethylene-butene copolymerElastomerCrystallinityStress-strainThe crystallinity of ethylene-butene copolymers prepared by copolymerization of ethylene and butene in the presence of a new highly active catalyst was studied by means of DSC, WAXD and DMA. The results show that the melting temperature, the cr...
A polyolefin blend having in a range of 40 to less than 90% by weight of a high modulus, isotactic polypropylene; and in a range of 10 to 60% by weight of a 1-butene/ethylene copolymer; the 1-butene/ethylene copolymer having about 0.5 to about 10 wt % of an ethylene. A polyolefin...
1. Fig. 1 Catalyst encapsulation approach for ethylene polymerization in water. Our technical approach consists of first, encapsulating an olefin polymerization catalyst in micelles formed by an amphiphilic block copolymer and second, performing the polymerization of ethylene within these micelles to yield...
