Abstract
The invention relates to a process for synthesizing a block polymer of formula AB-(C)n, wherein the symbol A represents a poly(1,3-cyclohexadiene) block, the symbol B represents a statistical copolymer block comprising units of a 1,3-diene and more than 50 mole percent of ethylene units, and the symbol C represents a polyethylene block, n being equal to 0 or 1, the 1,3-diene being an α-olefin. The invention also relates to a block polymer of formula AB or ABC obtainable by the process of the invention, the symbol A representing a poly(1,3-cyclohexadiene) block with a glass transition temperature above 120°C, the symbol B representing a statistical copolymer block comprising units of a 1,3-diene and more than 50 mole percent of ethylene units, and the symbol C representing a polyethylene block, the 1,3-diene being an α-olefin.
