The solid state structure and properties of homogeneous copolymers of propylene and 1-hexene were studied by examining melting behavior, dynamic mechanical response, and morphology primarily with atomic force microscopy, wide- (WAXS) and small-angle

The electrical conductivities of various polyolefins filled with a high-structure carbon black (CB) were studied. Typical percolation behaviors were observed in all of the materials studied. At a critical CB content, which defined the percolation thr

The solid-state structure and properties of homogeneous copolymers of propylene and 1-octene were examined. Based on the combined observations from melting behavior, dynamic mechanical response, morphology with primarily atomic force microscopy, X-ra

Films with a thousand alternating layers of isotactic polypropylene (PP) and polystyrene (PS) were prepared by layer-multiplying coextrusion. The crystal structure of extremely thin PP layers confined between PS layers was studied by optical light mi

The immiscible polypropylene (PP)/natural rubber (NR) blends of various concentrations were prepared by using a twin-screw extruder. The prepared blends were passed through the reactor where they were ultrasonically treated by an extrusion process. M

This study examined the oxygen-transport properties of poly(ethylene terephthalate-co-bibenzoate) (PETBB55) crystallized from the melt (melt crystallization) or quenched to glass and subsequently isothermally crystallized by heating above the glass-t

In the present study we examined the oxygen-transport properties of poly(ethylene naphthalate) (PEN) isothermally crystallized from the melt (melt crystallization) or quenched to the glass and subsequently isothermally crystallized by heating above t

Copolymers of ethylene glycol with 4,4′-bibenzoic acid and terephthalic acid are known to crystallize rapidly to surprisingly high levels of crystallinity. To understand this unusual behavior, the isothermal crystallization of poly(ethylene bibenzo

The unexpectedly long time scale for development of melt adhesion strength in blown films of molecularly heterogeneous Ziegler−Natta ethylene copolymers previously led to speculation on the existence of a surface layer enriched in low molecular wei

Structure-property relationships were studied in a series of hyperbranched polyesters based on dimethoxypropionic acid with ethoxylated pentaerythritol as the core. In DSC thermograms, all the polyols exhibit a prominent glass transition and a small
