The role of polyoxyethylene triol,rosin polyester polyol and asphalt in the asphalt-polyurethane rigid foam was stressed.
The ratio of rosin and rosinate is the important effect factor to the properties of sizing in the rosinate neutral sizes.The best weight ratio is 40%~50%.
From rosin purified abietic acid was prepared by using abietic acid as stared material acylamino surfactant was synthesized by maleric anhydride and diethanolamine.
The authors discuss the applications of rosin and its derivant,including nonsulfide flotation and flotation separation of nonferrous metallic ions and organic compound from aqueous solution.
