polyethylene [pol″e-eth´ĭ-lēn] polymerized ethylene, (—CH2—CH2—)n, a synthetic plastic material, forms of which have been used in reparative surgery. Definition: A linear polymer of the simple ethylene molecule synthesized as a fine white powder. Definition of Polyethylene Terephthalate “A polyethylene terephthalate is a condensation polymer of both terephthalic acid and ethylene glycol.” The reaction’s by-product to create this compound is water, and so it is an example of step-growth polymerization or condensation. 1-butene, 1-hexene, and 1-octene). You may be wondering what the n represents in the first image. Polyethylene is used in applications ranging for films, tubes, plastic parts, laminates, etc. The chemical formula of polyethylene is (C 2 H 4) n. Polyethylene is a combination of similar polymers of ethylene with different values of n. A typical polyethylene molecule can contain more than 500 ethylene subunits. Polyethylene definition is - a polymer of ethylene; especially : any of various partially crystalline lightweight thermoplastics (CH2CH2)x that are resistant to chemicals and moisture, have good insulating properties, and are used especially in packaging and insulation. Polyethylene chemical formula is (C 2 H 4) n. Methane gas (Figure 1-1a) is Ethylene consists of covalently bound carbons and pendant hydrogens. Manufacture: LLDPE (Linear-Low Density Polyethylene) is defined by a density range of 0.915 - 0.925 g/cm 3. is a substantially linear polymer, with significant numbers of short branches, commonly made by copolymerization of ethylene with short-chain alpha-olefins (e.g. Based on this mechanism, there are two types of polymerization.
