14.5 Below, molecular weight data for a polypropylene material are tabulated. What is the “mer” of PP? Mer molecular weight of PP is Example 1 C 3 H 6 m o =3A C +6A H =3(12.01 g/mol)+6(1.008 g/mol) = 42.08 g/mol Number avg degree of polymerization n n = M n m o = 10 6 g /mol 42.08g /mol = 23,700 Problem 1 (a, b, and c) A. Here the covalent bonding occurs by an S N 2 reaction between a nucleophile, usually an amine, and a terminal epoxide. Example 1 Mer molecular weight of PP is C3H6 mo =3AC+6AH =3(12.01 g/mol)+6(1.008 g/mol) = 42.08 g/mol Number avg degree of polymerization 700, Step-growth polymerization is also used for preparing a class of adhesives and amorphous solids called epoxy resins. The effect of hydrogen and external electron donor on polypropylene microstructure was investigated at two polymerization temperatures. James J. Brader, Determination of the degree of helical structure and related isotacticity of polypropylene by an infrared method, Journal of Applied Polymer Science, 10.1002/app.1960.070030919, 3, 9, (370-371), (2003). Compute the number-average degree of polymerization for polypropylene, given that the number-average molecular weight is 1,000,000 g/mol. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. (b). In linear polymers the individual polymer chains rarely have exactly the same degree of polymerization and molar mass, and there is always a distribution around an average value. Polypropylene, a synthetic resin built up by the polymerization of propylene. Compute (a) the number-average molecular weight, (b) the weight-average molecular weight, and (c) the degree of polymerization. Degree of polymerization is which one of the following: (a) average number of mers in the molecule chain; (b) proportion of the monomer that has been polymerized; (c) sum of the molecule weights of ... polypropylene, (d) polystyrene, or (e) polyvinylchloride? Calculate the degree of polymerization for polypropylene with a total molecular weight of 5x10^3 Da. It is produced via chain-growth polymerization from the monomer propylene.. One of the important family of polyolefin resins, polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. The polypropylene samples were characterized using high-temperature gel permeation chromatography (GPC), carbon-13 nuclear magnetic resonance (13C NMR), and crystallization elution fractionation (CEF). Weight average molecular weight (M W) and number average molecular weight (M N) are two ways we can characterize the polymer molecular weight.Polymer M W is defined as follows. Polymer molecular weight is defined as a distribution rather than a specific number because polymerization occurs in such a way to produce different chain lengths. A common means of expressing the length of a chain is the degree of polymerization, which quantifies the number of monomers incorporated into the chain. High degree of short and long chain branching Density - 30.910–0.940 g/cm Lower tensile strength and increased ductility Free radical polymerization Plastic bags and film wrap High Density Polyethylene (HDPE) Low degrees of branching (essentially linear) Density > 0.940 g/cm3 High tensile strength Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg.
