  • Preparation of phenylphosphate esters of 4,4'-biphenol
    Publication number: 20030171463
    Abstract: A process for preparing 4,4′-biphenol phenylphosphate ester products is described. These ester products, having low acid value and low contents of phenol and residual catalyst, being flowable powders, and further having excellent physical properties such as heat and hydrolytic stability, are useful as halogen-free, effective flame retardants, particularly in thermoplastic polymer compositions.
