Abstract: In this paper，research progress of polymer materials modified by rosin is reviewed. Preparation and application of rosin-modified phenolic resin，polyurethane，poly-acrylic acids，alkyd resin and other polymer materials are introduced. Advantages and disadvantages of one-step and two-step methods of making rosin-modified phenolic resin are compared. Semi-continuous seed emulsion polymerization method/mini-emulsion prepared rosin modified polyacrylate polymer materials are also introduced. In order to promote the development of rosin modified polymer material，the development trends of polymer materials modified by rosin is predicted，the development potential of light color and high softening point polymer materials based on modification of the double bond and carboxyl group of rosin is discussed.

Key words: rosin, polymer material, application, modified
