STRUCTURE OF POLYSULPHONE-NYLON 6 BLOCK COPOLYMER FILM
聚砜-尼龙6嵌段共聚物结构的研究

The structure of polysulphone-nylon 6 block copolymer film was studied by inverse GC, electron microscope and polarizing microscope. The heat of adsorption of water on the surface of this block copolymer was determined by IGC. Experimental results show that the crystallinity of nylon 6 is decreased by the addition of polysulph-one component, and the copolymer formed is composed of nylon 6 crystal domains and amorphous domains comprising both nylon 6 segments and polysulphone segments. IGC results also show that the compatibility of the two components is relatively poor.
