Six aromatic polyesters were prepared for gas separation membranes, and their per-meation properties for hydrogen, oxygen, nitrogen, carbon dioxide, and methane
The photophysical behaviors of the oligomer based on 1,1’-binaphthol with3,3’-acetylene spacer were investigated. The oligomer molecule has a naphthyl-acetyle
The photopolymerization of two kinds of prepolyesters containing conjugated diacetylene (PDA-6 and PDA-12)was investigated using DSC. By measuring the endotherm
This paper mainly deals with the design and synthesis of a novel styrene-butadieneblock copolymer. When this copolymer is used in the tread portion of tyres, it
