The crystallization porperty of polycaprolactam(PA6)-polyethylene glycol(PEG)block copolymer wasinvestigated by means of electron microscope,x-ray diffraction,DSC and hot stage polarized microscope.
The effect of ethylene comonomer content on the crystallization, mechanical and viscoelastic properties of VERSIFY copolymers was studied by DSC, DMTA, POM and WAXD.
During heating,phase transformation and expansibility of the new quartz sands and the calcined Quartz sands from two places were determined by DSC and thermodilatometry.
Using lead benzoxy as curing agent,cured epoxy resin was analyzed by means of IR spectrum and DSC curves.Lead benzoxy was considered to be catalytic curing agent.
Abstract: Using lead benzoxy as curing agent,cured epoxy resin was analyzed by means of IR spectrum and DSC curves.Lead benzoxy was considered to be catalytic curing agent.
The photographs of polarizing microscope showed the number of spherocrystal was increased and the diameter was decreased after saponification reaction which was agreed with the studies of DSC.
