Abstract: 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.

Abstract translation: 本发明涉及包含至少一个PA嵌段和至少一个PB嵌段的嵌段共聚物。 PA嵌段代表包含一个或多个单体单元A的聚合物嵌段，PB嵌段代表包含一个或多个单体单元B的聚合物嵌段。单体A是乙烯基，丙烯酸，二烯烃，腈，二腈或丙烯腈单体 。 单体B是含有一种或多种甘油三酯的可自由基聚合的植物油单体。 本发明还涉及通过在引发剂和过渡金属催化剂体系的存在下，使自由基聚合性单体与含有一种或多种甘油三酯的自由基聚合性植物油单体自由基聚合来制备热塑性嵌段共聚物的方法，以形成 热塑性嵌段共聚物。 聚合植物油基嵌段共聚物可用于各种应用，例如沥青改性剂，橡胶组合物，粘合剂，轮胎，汽车工业，鞋类，包装等。
