WebPhosphonite stabilizer composition means the compositions marketed under the trademark Sandostab P-EPQ by Sandoz Chemicals Ltd., the main component of which is tetrakis-(2,4-di-tert-butylphenyl)-4,4-biphenylene diphosphite. Such compositions are commercially available. DETAILED DESCRIPTION OF THE INVENTION WebAlkyl phosphite esters are used in the Perkow reaction for the formation of vinyl phosphonates, and in the Michaelis–Arbuzov reaction to form phosphonates. Aryl phosphite esters may not undergo these reactions and hence are commonly used as stabilizers in halogen-bearing polymers such as PVC .
