Abstract

Abstract: The raw material of rosin-type nucleating agent is a nature product with low cost,non-toxic,tasteless and high efficiency of excellent nucleation. It gradually becomes the modified agent of polyolefin resin that researchers are keened on. This paper summarized the recent advances on the nucleating agents of rosin and its derivatives for modifying some polyolefin resins,such as polypropylene,polyethylene,and the others. It is suggested that adding rosin-type nucleating agent is one of effective ways to modify the polyolefin resin. And the distinctions between the nucleating agent and traditional nucleating agent were also discussed,including its high temperature resistance,dispersion,environmental friendliness,and low cost. Meanwhile,the nucleation mechanism for decorating polyolenfin resin with rosin-type nucleating agent is discussed,and the solutions to poor dispersion problems were proposed,such as adding a certain amount of dispersant before extruding to granulate. Furthermore,using rosin type nucleating agent efficiently and exerting synergistic effects with a myriad of substances were introduced. Finally,the future development of rosin-type nucleating agent was proposed.
