ABSTRACT:
There are disclosed oxidation stable heteric or block copolymer polyoxyalkylene compositions suitable for the treatment of thermoplastic fibers, particularly polyester and nylon fibers, prior to the processing of such fibers in conventional processes to impart false twist, or to produce textured yarn or other type yarns by mechanical heat treatment and tensioning processes. The polyoxyalkylene compounds of the invention derived from lower alkylene oxides can be initiated with a difunctional aromatic compound containing reactive hydrogens such as a dihydroxyphenol to obtain an aromatic nucleus in the polymer chain and are capped on at least one end of the chain with an alpha-olefine epoxide or mixtures thereof with at least one aliphatic monocarboxylic acid. Hydroxyl functionality can be retained on one end of the molecule.
Alternatively, the polyoxyalkylene compounds of the invention can be derived from the polymerization of at least one lower alkylene oxide in admixture with an aromatic glycidyl ether wherein said polyoxyalkylene compound is produced by initiation of the polymerization with a base compound having one or more active hydrogen atoms and followed by end capping the chain of the polyoxyalkylene compound by reaction with an alpha-olefin epoxide or mixtures thereof with at least one aliphatic monocarboxylic acid.
In addition to the use of the oxidation stable polyoxyalkylene fiber lubricants of the invention alone or in admixtures with each other, said lubricants can be utilized in combination with fiber lubricants of the prior art wherein said mixtures contain a minor proportion of the oxidation stable fiber lubricants of the invention.
