ABSTRACT:
A waste stream of non-volatiles is recovered (NVR) as a by-product from the oxidation of cyclohexane to cyclohexanone and chlohexanol in the process for making adipic acid. The NVR is dehydrated, and then reacted with an esterifying polyol to form a polyester polyol which was found to be useful in the dispersion of vinyl resins. Those polyester polyols with low acid numbers of less than 10, and ,referably less than 2, were found to be most effective as vinyl dispersion plasticizers. A particularly useful end-product is a tough vinyl resin film having a Shore A hardness of approximately 55. End-products may also be used in wire coatings and coverings.
