The most common and thermodynamically favored chemical transformations of alkenes are addition reactions. (b). Degree of polymerization is which one of the following: (a) average number of mers in the molecule Determine the molarity of the following solution made up of … Generally has very good resistance to mineral acids; excellent resistance to common solvents, oils, greases, neutral salts, sunlight; fairly good resistance to weak alkalies but is degraded by strong alkalies. Flammability similar to that of rayon and cotton. It is a volatile organic compound and a member of formamides. Acrylonitrile | H2CCHCN or H2C(CH)CN or CH2=CH-CN or C3H3N | CID 7855 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. long-chain carbon-based "organic" molecules) which name refers to the fact that in their semi-liquid state they are malleable, or have the property of plasticity. Más tarde se alcanzó éxito utilizando fibras cortas de menor resistencia. This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right). What is the molecular or formula mass of the following: CH₃CO₂H (acetic acid) 60.06 amu. As long as we know the chemical formula of the substance in question, we can easily derive percent composition from the formula mass or molar mass. Acrylic acid (IUPAC: propenoic acid) is an organic compound with the formula CH 2 =CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. Properties. Polyester (Dacron) Acrylic (Orlon) C Nylon-6,6 O O CH2 CH2 H n H H n H n Wool (Protein) Figure 1. It is miscible with water, alcohols, ethers, and chloroform.More than a million tons are produced annually. Properties: White fiber. Sp gr 1.17. Petroleum products are used to produce synthetic fibers such as nylon, orlon, and dacron, and other polymers such as polystyrene, polyethylene and synthetic rubber. Ironing temps above 160° may cause yellowing. Chemical Structures of Fabric Molecules. Formula. Monomer. Example 2. Plastic covers a wide rage of synthetic or semi-synthetic polymerization products (i.e. La resistencia de las acrílicas a los tintes y el alto costo de producción limitó su uso en estos usos finales. Dyes are classified based on both the structure of the dye and the way in which the dye is applied to the fabric. But what if the chemical formula of a substance is unknown? What is the molecular or formula mass of the following: C₁₂H₂₂O₁₁ (sucrose, cane sugar) ... Orlon; 67.9% C, 5.70% H, 26.4% N. C₃H₃N. Unit - Chemistry of Garments: Synthetic (man-made) Fibres Acrylic, Aramid ( Twaron, Kevlar, Technora, Nomex), Microfiber, Modacrylic, Nylon, Olefin Polyester, Polyethylene ( Dyneema, Spectra), Spandex, Vinylon, Vinyon, Zylon Nylon (Polyamide) Nylon is a thermoplastic silky material, first commercially used in a nylon-bristled toothbrush (1938). Answer. ... Orlon; 67.9% C, 5.70% H, 26.4% N. A major textile dye manufacturer developed a new yellow dye. Sticks at 235°. Given the chemical formula of the substance, we were able to determine the amount of the substance (moles) from its mass, and vice versa. It has a role as a polar aprotic solvent and a hepatotoxic agent.
