Phenol type antioxidant be oxidated to hydroquinones type structure. The color appear as yellow or dark-brown
Phenolic polymer = made of phenylpropanoid subunits (called monolignols) which are derived from phenylalanine
i make the phenolic foam out of both of them in the same formula it works out fairly well but i am engineering it to get top performance out of the polymers.
An arylsulfotransferase is a sulfotransferase enzyme which transfers a sulfate group from phenolic sulfate esters to a phenolic acceptor substrate.
Thermoset
Castor nut oil would be a good start
A biphenol is any compound which has two phenolic hydroxy groups, such a phenolic derivative of biphenyl.

An arylsulphotransferase is a a sulphotransferase enzyme which transfers a sulphate group from phenolic sulphate esters to a phenolic acceptor substrate.

Phenolic resin is less costly and easier to work with than epoxy. Many epoxy resin systems have a very short pot life.
Thermoset
The phenolic compound has a great effect on one psychological state. However, this is not the only effect is has on people.
Phenolic resins are used in the production of circuit boards. Phenolic resin based paints are mainly metal paints, formed with the combination of epoxy resins. You can apply these paints on metals with different techniques.
abd. distention, Yellowing of the skin, yellowing of the white of the eyes
yellowing in vinyl usually means the plasticizes in the product have reacted to something ie. water or solvent. this yellowing can not be removed sorry.
acetone
