Due to the great intermolecular force of nylon tie polymer compounds, their liquid viscosity is very large, and they often exist in solid state, so it is difficult to exist in gaseous state.
When the nylon tie polymer material has tensile failure The molecular chain always breaks first (covalent bond breaking sheet rather than molecular sliding comes first. Intermolecular force has a great impact on the strength, elasticity, drillability and physicochemical properties of polymer materials, especially on the strength of nylon binding materials. Generally speaking, the structural polymer of amorphous polymer has large molecular weight, high crystallinity, strong polarity and easy to form hydrogen bond, so the intermolecular force is large and the material strength is high. However, increase the molecular weight The intermolecular force and material strength cannot be infinitely improved. When the molecular t increases to a certain degree (different types of Lang compounds, different values), even if the molecular weight is increased, it will not have a significant impact on the intermolecular force and material strength.
