  • Functional diene polymers, their method of preparation and their use in silica-filled elastomeric compositions which can be used for tires
    Patent number: 5665812
    Abstract: A sulfur-vulcanizable rubber composition of improved hysteresis, comprising ilica as reinforcing filler as well as a diene polymer functionalized with a functionalizing agent having the general formula (Y).sub.m --R.sup. --Si(OR.sup.2).sub.3-n --R.sup.3 n and suitable to be used for the manufacture of tires of reduced resistance to rolling.The functionalized diene polymers are prepared by addition to the living diene polymer under suitable mixing conditions of an amount of functionalizing agent such that the molar ratio of functionalizing agent to the number of active sites is equal to or greater than 1.
