Zaki Tawfeeq W. Salih 1) Materials Engineering Department, College of Engineering, Mustansiriyah University, Baghdad, Iraq Abstract: The aim of this research is investigating the physical, mechanical, and chemical properties direct effect of crystallinity of thermoplastic polymers on [1]. The most useful classification of polymers their thermal conductivity values. The study has included for engineering purposes is based on their many materials, namely: polyoxymethylene (POM), high- thermo-physical reaction. Polymers are known as density polyethylene (HDPE), low-density polypropylene thermoplastics or thermosets in this scheme. (LDPE), polypropylene (PP), polyamide (PA) and Thermoplastic polymers, as the name implies, polyethylene terephthalate (PET). The degrees of melt and flow when subjected to heat and strain. crystallinity ranged from high-values (60-70%), mid-values (30-40%) and low-values (10-20%). The work has done Polyethylene, polystyrene, and nylon are theoretically and experimentally. Theoretical work has examples of thermoplastic polymers. used mathematical function extracted from reliable Crystallinity refers to the degree of structural empirical relationships. The experimental work has order in a solid.
