(1) They are then treated with a reacting compound that causes the molecules to polymerize and change the color of hair.(2) this was baked until the sulphur began to polymerize(3) The principal reason for this is the unsaturated nature of the alkene that allows the double bond to polymerize and to participate in many other reactions that the saturated alkanes cannot.(4) Glucose loses two water molecules and rearranges to form hydroxymethyl furfural, which polymerizes into brown pigments that add flavor and color to the candy.(5) The polymerization of an ester can produce a polyester, an artificial fiber that is used as a cotton substitute.(6) They could have been produced by the photodissociation and polymerisation of atmospheric molecules, such as carbon dioxide, methane and ammonia, through a combination of high temperature, ultraviolet light and bolts of lightning.(7) In free radical polymerization , monomers can add to each other without formation of a small molecule.(8) These unsaturated hydrocarbons are readily oxidised and polymerised , which can reduce the oil's shelf life.(9) For example, polystyrene is the material that results from the polymerization of styrene monomers.(10) This stabilizing effect has been observed in solid copolymers of methacrylate monomers with Rhodamine 6G analogs containing polymerizable groups in their structure.(11) This will cause exponential network growth until the pool of polymerizable G-actin is locally depleted.(12) In the free radical polymerization of ethylene to form polyethylene, a small amount of a peroxide is added to a large volume of ethylene.(13) Other resins do have polymerizable components and dry by a combination of essential oil loss and polymerization.(14) The particle movement can be simulated in cell-free systems by incubating beads that are coated with N-WASP, an activator of the Arp2 / 3 complex, in a mixture of polymerizable actin and four other essential proteins together with ATP.(15) Bacterial fermentation of carbohydrates produces lactic acid, and this in turn can be chemically polymerised to a high molecular weight PLA polyester.(16) These data suggest that, similar to salt-induced polymerization, the filament assembly by S1 involves an initial ‘monomer activation’ step transforming G-actin into polymerizable species.
