Ziegler-Natta catalyzed polymerization kinetics : origin of the molecular weight distribution
(1986)
The molecular weight distributions generated by Ziegler-Natta catalyzed polymerizations are examined. Only those catalysts with one type of catalytic species are considered. From the rate laws for propagation and elimination, ...
Functionalization of polyolefins : entrapment of functionalized ethylene oligomers in polyethylene
(1985)
Functionalization of polyethylene by entrapment of functionalized ethylene oligomers in precipitates of polyethylene is described. The details of this entrapment process, which is an alternative to harsh, unselective ...
Characterization of the electrode/electrolyte interphase of the electronically conducting polymer, polypyrrole
(1990)
An investigation was made to characterize the structure of the interphase of polypyrrole in terms of semiconductor theory and the molecular structure of the polymer. This investigation was carried out by performing experiments ...
Syntheses and applications of functionalized hydrocarbon oligomers and polymers
(1986)
Both cross-linked polystyrene and linear ethylene oligomers were investigated as supports for reagents and catalysts. Use of either of these polymers as supports, reagents or catalysts had certain advantages. Selection of ...
The role of the substrate in ion formation produced by fast heavy ion induced desorption
(1991)
The desorption-ionization of organic and inorganic ions ejected from polymer and metal-coated polymer surfaces with salt overlayers was studied using [252]Cf plasma desorption mass spectrometry. The matrix, when bombarded ...
Solid-state nuclear magnetic resonance studies of phosphazene inorganic polymers
(1989)
Polyphosphazenes are inorganic polymers which are based on chains of alternating phosphorus and nitrogen atoms. These materials are of considerable interest because of their mechanical and thermal properties, solvent ...
Synthesis, ligand properties, and interfacial chemistry of metal carboxylate terminated oligomers of polyethylene
(1991)
Ethylene oligomers functionalized at their terminus with metal carboxylates were prepared. These oligomers were used to study ligation of metals by soluble metal carboxylates. They were also used to study chemistry at ...
Study of the morphology and its effects on the mechanical properties of linear low density polyethylene
(1992)
A linear low density polyethylene, with 1-octene as the co-unit, forms a semicrystalline matrix when cooled from the melt. This matrix is composed of a spherulitic superstructure with a lamellar microstructure. The careful ...
