PHENOLIC RESIN AND POLYETHER TREATED GUAYULE RESIN AND RUBBER COMPOSITIONS CONTAINING THE SAME |
摘要 |
Guayule-type resins are chemically treated with a reactive phenolic resin and a polyether such as an amine terminated polyether. The treated guayule resin has improved physical properties such as higher softening points. The resulting composition is suitable as a rubber additive since it improves various physical properties such as building tack, tear strength hysteresis loss, and the like. |
