Application
在轮胎制造中，聚丁二烯主要是与天然橡胶和苯乙烯丁二烯橡胶混合。它也可用于开发传送带和传动带。
General description
聚丁二烯是一种合成橡胶，通过1.3-丁二烯的溶液聚合生产。它具有良好的机械性质，包括低温弹性和耐磨性。它可以用硫基供体和过氧化物固化，从而得到具有高交联度的高弹性聚合物。

Controlled/"living" polymerizations and tandem polymerization methodologies offer enticing opportunities to enchain a wide variety of monomers into new, functional block copolymer materials with unusual physical properties. However, the use of these synthetic methods often introduces nontrivial molecular weight polydispersities, a
