@Pelestears- The difference between emulsion and solution polymerisation is a bit difficult to explain in simple terms, but I will try. I will assume that you understand solution polymerization as explained in the article. Emulsion polymerization is a free radical polymerization reaction that basical...
What is the name of a hydrocarbon having 6 carbons and a triple bond? What is the main source of hydrocarbon? What functional groups besides alkane and cycloalkane are present in the following molecule? Which groups of hydrocarbons would lead to: Addition polymerisation. ...
example, polythene, polystyrene, pvc, nylon and dacron. 2. classification based on synthesis addition or chain polymers – it involves the repeated addition of monomers to the polymer chain. the monomers are unsaturated compounds. the monomer and the chain growth polymerization compound is tabulated ...
At wine pH, glyoxylic acid reacts reversibly with hydrogen sulfite to form a relatively stable addition product, also known as an α-hydroxy sulfonate, resulting, in wine, in a decrease in the amount of free sulfur dioxide. For hair Glyoxylic acid (GA) is widely used as a straight per...
In addition, the amount of energy needed to start a reaction is the activation energy. This energy is required to form the transition state, which occurs when reactant molecules collide, and the rate constant, k, is related to temperature by the Arrhenius equation. Process Analytical ...
Epoxy resin curing may either involve a reaction with itself (homopolymerisation) or the formation of a copopolymer featuring polyfunctional hardeners or curatives. Varieties of epoxy resin hardeners include thiols, alcohols, phenols, acid anhydrides, acids, and amines. The respective levels of react...
Paraloid® B72, an acrylic-based resin obtained from a free radical polymerisation reaction between ethyl methacrylate (EMA) and methyl acrylate (MA), was used as a protective coating. Microscopic observations showed that the resin was applied in large quantities on the damaged surface of the ...
A dispersion polymerization is one in which the monomer-initiator are soluble in the reaction medium, while the polymer formed is insoluble and the majority of effective CO2-soluble stabilisers for dispersion polymerisation in scCO2 have been fluorinated or silicone-based polymers [3]. [7] reported...
These considerations will include the effects of smoke and toxic decomposition products on people, property and equipment. PU foams used in furniture are an example which spring to mind. Fire retardancy can be achieved by the addition of fluorine, chlorine, bromine or iodine compounds to the polyo...
