We developed newly designed polypropylene polyol with terminated primary hydroxyl group. We focus on our new polypropylene polyol, and show its useful application for polyurethane foam. Polymerization of propyleneoxide is conventionally carried out in anionic polymerization process. In anionic process α-cleavage of propyleneoxide occurs rather than β-cleavage. Then the terminal hydroxyl group of the resulting polypropy... 展开更多
