Since the earliest discovery and subsequent developments in the world of polymers associated problems and increasing applications have resulted in the rapidly expanding field of “additives.” In this context, the term additive is very generalized in that it encompasses many facets associated with ever growing needs. Of the most important are antioxidants (primary and secondary), light stabilizers, processing aids, metal deactivators, flame retardants, biocides, nucleating agents, antistatic compounds, fillers, dyes, pigments (nano, micro, and macro) to name but only a few each serving a particular function and not necessarily all at the same time in the one package. This article presents a general perspective on the type, mode of action, properties, uses, and problems (and circumvention) based on some of the more important key additives. The properties and behavior of many additives in this regard relates very much to the initial incorporation and formulation and in turn is often a major controlling factor in end use performance from a physical, esthetic, structural, mechanical, and chemical point of view. Indeed, with many polymers like PVC, for example, one enters a highly complex world of interactions which can in many cases destroy or even enhance the activity of functional processing additives. Some of these will be highlighted and hopefully the aim being here to enthuse the polymer and additive manufacturers and technologists in the processing laboratories to become more aware of potential issues and problems.

关于聚合物添加剂的观点。1.稳定方面

自从与世界相关的问题的最早发现和随后的发展以来,与问题相关的问题和越来越多的应用导致“添加剂”领域的迅速发展。在这种情况下,术语“添加剂”非常笼统,因为它涵盖了与不断增长的需求相关的许多方面。最重要的是抗氧化剂(主要和次要),光稳定剂,加工助剂,金属减活剂,阻燃剂,杀生物剂,成核剂,抗静电化合物,填充剂,染料,颜料(纳米,微观和宏观),但仅此而已。在一个程序包中,很少有每个程序可以提供特定功能,而不必同时全部执行。本文介绍了基于一些更重要的关键添加剂的类型,作用方式,性质,用途和问题(以及规避)的总体观点。在这方面,许多添加剂的性质和行为与初始掺入和配制非常相关,从物理,美学,结构,机械和化学的角度来看,它们反过来往往是最终使用性能的主要控制因素。的确,例如,对于许多聚合物,如PVC,人们进入了一个高度复杂的相互作用世界,在许多情况下,它们可能破坏甚至增强功能性加工添加剂的活性。其中一些将被突出显示,希望这里的目的是激发加工实验室中的聚合物和添加剂制造商和技术人员更多地意识到潜在的问题。
