How does flammability depend on chain length
WebHowever, whenever a synthetic polymer is made, chains of varying length (varying n’s) are produced, and the product has a range of formula weights. Therefore, the “molecular weight” is really an average for the sample. To complicate the situation, there are several types of averages, depending on how the molecular weight is measured.

WebAug 3, 2024 · An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties. WebJan 23, 2024 · Boiling points of alkenes depends on more molecular mass (chain length). The more intermolecular mass is added, the higher the boiling point. Intermolecular forces of alkenes gets stronger with increase in the size of the molecules. In each case, the alkene …
WebMay 13, 2024 · Flammability limits are not absolute, i.e. they do not depend on absolute atmospheric conditions; however, they do depend on the strength and type of the source … WebOct 4, 2008 · The flammability DECREASES as the chain length increases. Methane (C1) is natural gas and by definition very flammable. C20 is basically paraffin wax and it will burn …
WebA High molecular weight increases the chemical resistance - to a point. It takes more damage to the main chains of the molecules before it will affect the strength of the material. A High molecular weight increases the viscosity of the material – makes it harder to process the material using conventional methods.
