It is common practice to blend polymers to obtain high-performance polymer materials for new applications. Thermoplastic vulcanizates (TPVs), consisting of a high content of crosslinked rubber as a dispersed phase and a low content of thermoplastic as a continuous phase, are usually prepared by pre-blending rubber and plastic phases followed by dynamic vulcanization. They are a special class of high performance thermoplastic elastomers (TPEs) as they combine both the excellent elasticity and mechanical properties of crosslinked rubbers and good processability and recyclability of thermoplastics. As such, in the recent decades they have attracted much attention and have become the fastest growing elastomers to replace unrecyclable thermoset rubbers. This review focuses on recent progresses in TPVs, and more specifically on the following issues: (1) preparation methods of TPVs, (2) mechanisms of formation of the microstructure of TPVs; (3) relationships between the microstructure and properties, (4) review of various types of TPVs, including general TPVs, special TPVs, bio-based TPVs, and TPVs-based nanocomposites, (5) future challenges on TPVs.

通常的做法是共混聚合物以获得用于新应用的高性能聚合物材料。热塑性硫化橡胶（TPV）通常由预混合的橡胶和塑料相，然后进行动态硫化来制备，其中高含量的交联橡胶为分散相，低含量的热塑性塑料为连续相。它们是一类特殊的高性能热塑性弹性体（TPE），因为它们兼具交联橡胶的出色弹性和机械性能以及热塑性塑料的良好加工性能和可回收性。因此，在最近的几十年中，它们已引起人们的广泛关注，并已成为增长最快的弹性体，以替代不可回收的热固性橡胶。这篇评论着重于TPV的最新进展，尤其是以下问题：（1）TPV的制备方法，（2）TPV微观结构的形成机理；（3）微观结构和性能之间的关系，（4）审查各种类型的TPV，包括通用TPV，特殊TPV，生物基TPV和TPV基纳米复合材料，（5）TPV的未来挑战。
