The lamellar structure of a thermotropic aromatic polyester with flexible spacer has beenstudied by using transmission electron microscopy. It was found that th
The non-isothermal crystallization kinetics of poly(ethylene terephthalate) (PET) modified by poly (ethlene glycol) (PEG) were determined by DSC. The dual linear regres
Various catalysts for the polymerization ot aromatic nitriles were investigated. It was found that Lewis acid-metal is a preferable catalyst system for the poly
A series of porous microspheres of linear and ethylene diacrylate (M’) cross-linked copolymers of 2-vinylpyridine (V) and methyl acrylate (M) reacted with tetr
