What is the shape polymer? How do their characteristics?
Is a linear polymer chain to react the functional group under certain conditions by the AFL-CIO, or by the direct polymerization of monomer three-dimensional structure of the polymer. Polymer body is a “giant molecule” molecular size and molecular weight are not a limit, often a product is a huge volume of molecules. Therefore, the molecular weight it has lost its meaning. It can not be dispersed by the solvent molecules (but can be solvent swelling), heat can not flow, is insoluble compounds. Amorphous polymer body is always in the glassy state, very hard, brittle, usually not to show flexibility, heat does not soften, it does not work plasticizer, cold rolling and not to delay or molecular orientation. However, due to the formation of polymer shape is often carried out in stages, from a linear shape by the shape and the last, if the structure has not yet formed in the body to die before that, while heating, allow the reaction to complete the course in full bloom can be be hard products. General commonly referred to as thermosetting plastics, mostly polymer body.
