Crosslinked species are found in all three categories and the process of crosslinking may change the cited characteristics of the categories. Thus, plastics are known to possess a marked range of deformability in the order of 100 to 200%; they do not exhibit this property when crosslinked, however. Rubber, on vulcanization, changes its properties form low modulus, low tensile strength, low hardness, and high elongation to high modulus, high tensile strength, high hardness， and low elongation. Thus, polymers may be classified as noncrosslinked and crosslinked, and this definition agrees generally with the subclassification in thermoplastic and thermoset polymers. From the mechanistic point of view, however, polymers are properly divided into addition polymers and condensation polymers. Both of these species are found in rubbers, plastics, and fibers.

被交互相联的种类被发现在所有三个类别并且交互相联的过程也许改变类别的被援引的特征。因而, 塑料知道拥有deformability 的一个明显范围按100 到200% 的顺序; 他们不陈列这物产当交互相联, 然而。橡胶, 在硫化作用, 改变它的物产形式低模数、低抗拉强度、低坚硬, 和高伸长到高的模数, 高抗拉强度, 高坚硬? 并且低伸长。因而, 聚合物也许被分类和noncrosslinked 和交互相联了, 并且这个定义一般与subclassification 一致在热塑性塑料和thermoset 聚合物里。从机构观点, 然而, 聚合物适当地被划分成加法聚合物和结露聚合物。这两个种类被发现在橡胶、塑料, 和纤维。 在许多情况下聚合物被考虑从机构观点。并且, 聚合物将被命名根据它的来源每当它从一个具体假定单体被获得, 或当它从任意地被建立入聚合物的二个或更多组分被获得。这个分类很好与目前半新一般实践一致。当重覆的单位由几个monomeric 组分组成跟随有规律的方式, 聚合物共同地被命名根据它的结构。
