The present invention relates to a block copolymer comprising at least one PA block and at least one PB block. The PA block represents a polymer block comprising one or more units of monomer A and the PB block represents a polymer block comprising one or more units of monomer B. [ Monomer A is a vinyl, acrylic, diolefin, nitrile, dinitrile or acrylonitrile monomer. Monomer B is a radically polymerizable vegetable oil monomer comprising at least one triglyceride. The present invention also provides a process for preparing a thermoplastic block copolymer by radical polymerizing a radically polymerizable monomer in the presence of a radically polymerizable vegetable oil monomer comprising at least one triglyceride and an initiator and a transition metal catalyst system to form a thermoplastic block copolymer ≪ / RTI > The polymerized vegetable oil based block copolymers are useful in asphalt modifiers, rubber compositions, adhesives, tires in a variety of fields, such as the automotive industry, footwear, packaging, and the like. |
