Contrast polymers that have an amorphous arrangement with those that have a crystalline arrangement in terms of structure and properties . 7. Give at least two reasons why polymers are used for the following: a. Certain special types of polymers have emerged as very useful class of polymers having their own special chemical properties and applications in various areas. These “stimuli-responsive” polymers (SRPs) have been variously called stimuli-sensitive [1], intelligent [2], smart [3,4], or environmentally-sensitive polymers [5]. 翻訳 · Be it as packaging, in automobiles and above all in the electrical, electronics and toy industries. The properties of the plastics are very different, from extremely rigid to extremely flexible, everything is possible – and in the most diverse colors.
