Low density polyethylene (LDPE)/poly(ethylene terephthalate) (PET) multilayer films with and without a reactive tie layer were prepared by blowing process. The layers contents were fixed and the parameters evaluated were blow-up ratio (BUR), draw-down ratio (DDR) and frost-line height (FL). Their effect on the structure was studied. No crystallinity for the PET layer was induced by the blowing process...
Shear modulus of polyacrylamide (PAAM) gels has been measured with the network concentration ranging from 0.02 to 1.0 g/cm 3 . In the low concentration region, the shear modulus is a scaling function of network concentration with the exponent equal to 13, which is expected by classical rubber elasticity theory. As the concentration increases, the behaviour of shear modulus deviates the scaling...
Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to examine the morphology of blends of PA1010 and polypropylene (PP) compatibilized with polypropylene grafted with glycidyl methacrylate (PP-g-GMA). It is found that the morphologies are dependent on the content of glycidyl methacrylate in PP-g-GMA and the mixing time. The size of the dispersed PP particles decreases...
Morphology, mechanical properties, and interfacial interaction of polyamide 1010/polypropylene (PA1010/PP) blends compatibilized with polypropylene grafted with glycidyl methacrylate (PP-g-GMA) were studied. It was found that the size of the PP domains, tensile and impact strength of ternary blends, and adhesion fracture energy between two layers of PA 1010 and PP were all significantly dependent...
