    摘要： The present invention relates to a method of preparing a multiblock copolymer. This method comprises i) providing a block copolymer comprising at least one PA block and at least one PB block, where PA represents a polymer block comprising one or more units of monomer A and PB represents a polymer block comprising one or more units of monomer B, with monomers A and B being the same or different, where the block copolymer contains a chain transfer agent moiety (CTA); ii) providing a radically polymerizable monomer C; and iii) polymerizing the block copolymer with monomer C under conditions effective to achieve a number average degree of polymerization (Nn) for the multiblock copolymer of up to 100,000 without gelation. The present invention relates to a multiblock copolymer comprising at least one PA block, at least one PB block, and at least one PC block. PC block is positioned between PA block and PB block, where PC block is a rubber block, and where PA represents a polymer block comprising one or more units of monomer A, PB represents a polymer block comprising one or more units of monomer B, and PC represents a polymer block comprising one or more units of monomer C, with monomers A and B being the same or different.

    摘要： 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 plant oil monomer containing one or more triglycerides. The present invention also relates to a method of preparing a thermoplastic block copolymer by radical polymerizing a radically polymerizable monomer with a radically polymerizable plant oil monomer containing one or more triglycerides, in the presence of an initiator and a transition-metal catalyst system to form the thermoplastic block copolymer. The polymerized plant oil-based block copolymers are useful in a variety of applications, such as asphalt modifiers, rubber compositions, adhesives, tires, in the automobile industry, footwear, packaging, etc.
