OLIGOMERIC PHOSPHONATE COMPOSITIONS, THEIR PREPARATION AND USES

摘要

This invention provides oligomeric hydrogen phosphonates represented by the formula (I) where R is an alkyl group having one to about six carbon atoms; R' is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group having two to about twenty carbon atoms or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring, where at least one of R' is a linear or branched hydrocarbylene group or an oxygen-containing hydrocarbylene group and at least one of R' is a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; and n is a number from 2 to about 20. Also provided are processes for making these oligomeric hydrogen phosphonates, oligomeric organophosphonate compositions, and processes for making these oligomeric organophosphonate compositions.
