This invention relates to toluate ester compositions and their use as solvent, plasticizers, extender and/or diluents in binder formulations, a method of producing such ester compositions, as well as polymer compositions containing such liquid ester compositions. The method of making toluate based esters by reacting methyl-p-toluate with ethylene glycol, diethylene or triethylene glycol, butanediol, etc. More particularly, this invention relates to the mono-or di-ester of methyl toluic acid with a diol containing 2 to 6 carbon atoms that are low viscosity liquids at 25° C. The most common polymer that employs plasticizer is polyvinyl chloride (PVC). Typical amounts of plasticizer in PVC are from about 3 wt. % to about 50 wt. %. Phenolic resins generally require solvents, diluents and/or extenders that reduce the volatility and viscosity of the resin, especially when it is used in building and automotive products. Typical amounts of solvent are from about 5 wt. % to about 65 wt. %.
1) A toluate based ester useful as a plasticizer, extender, or diluent in polymer formulations, such as in binders, comprising:
8) A method of making a toluate-based diluent ester by reacting methyl-p-toluate with ethylene, diethylene, triethylene glycol, butanediol, or other aliphatic diols.
12) A composition of a polymer and toluate ester as plasticizer, diluent, or extender.
16)The composition of claim 14, wherein said natural oil is canola oil, castor oil, clove oil, coconut oil, corn oil, cottonseed oil, jojoba oil, linseed oil, olive oil, palm oil, peanut oil, safflower oil, sesame oil, soybean oil, or sunflower oil.
21) A foundry molding composition comprising:
