WebNylon is a generic designation for a family of synthetic polymers composed of polyamides (repeating units linked by amide links). Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes.: 2 Nylon polymers can be mixed with a wide variety of additives to achieve many property variations.

WebCondensation polymers are one of two products made in condensation polymerisation reactions, the other product being a small molecule (often water). The formation of cellulose is an example of a condensation polymerisation reaction: n (HO–C6H10O4–OH) → H– (O–C6H10O4)n–OH + (n – 1)H2O. In the formation of cellulose, n glucose ... WebA close look at the bonding in esters. You will remember that an ester is formed when a carboxylic acid reacts with an alcohol in the presence of some concentrated sulfuric acid …
WebThe chain grows by adding the reactive end of growing chain to double bond of monomer. Reactive intermediates such as free radicals, carbocations or carbanions are formed. An example of addition polymerisation is the polymerisation of tetrafluoroethylene (monomer) to form teflon (polymer). nCF 2=CF 2 polymerisation [−CF 2−CF 2−] n.
WebThis may seem too much if you are going over it first itme but one quick way of identifying these steps in radical halogenation is to keep track of the number of radicals: Initiation – goes from 0 radicals to two radicals. Propagation – goes from 1 radical to two radicals. Termination – goes from 2 radicals to 0 radicals. can i make food for my catWebAll the polymers could produce carbon monoxide if they don't burn completely.
