Polymer blends can be broadly divided into three categories: • immiscible polymer blends (heterogeneous polymer blends): This is by far the most populous group. If the blend is made of two polymers, two glass transition temperatures will be observed. • compatible polymer blends: Immiscible polymer blend that exhibits macroscopically uniform physical properties. The macroscopically uniform properties are usually caused by sufficiently st… WebAlloy steels Iron is alloyed with other metals to produce a range of alloy steels . Different steels have different properties , depending on their composition.

Webcompatible and alloys are mixtures that are fully compatible . Polymer alloy constitutes a specific sub-class of polymer blend; virtually all high performance engineering blends are … WebThe glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic changes in the physical and mechanical properties. Below Tg: Due to lack of mobility, the polymers are hard ... WebAnswer (1 of 5): Generally speaking, the term “alloy” refers to a mixture of metals. These are not polymers. However, there is such a thing as a polymer alloy although the use this terminology is frowned upon by academics.
