thermoplastic statistical copolymer, its method of preparation, compositions and vehicle tire The present invention relates to a thermoplastic block copolymer comprising at least one pa block and at least one bp block. block pa represents a polymer block comprising one or more monomer units a, and block pb represents a polymer block comprising one or more monomer units b. monomer a is a vinyl, acrylic, diolefin, nitrile, dinitrile, acrylonitrile monomer, a reactive functional monomer, or a cross-linking monomer. monomer b is a radically polymerizable triglyceride or mixtures thereof, typically in the form of a vegetable or animal oil. The present invention also relates to a method of preparing a thermoplastic block copolymer or novel thermoplastic statistical copolymers by polymerizing a radically polymerizable monomer with a radically polymerizable triglyceride or mixtures thereof by addition fragmentation chain transfer polymerization reversible (raft) in the presence of a free radical initiator and a chain transfer agent. |
