Abstract
In this study, phosphorus polyols, having a molecular weight of 880 to 1,560 g/mol, were synthesized by reacting phenylphosphonic dichloride (PPDC), allylphosphonic dichloride (APDC), and ethylene glycol (EG) in solvent, to enhance flame retardance of polyurethane. Phosphorus polyurethanes were polymerized using the synthesized phosphorus polyols, polycarbonate diol (PCD), and 4,4'-diphenylmethane diisocyanate (MDI) by a melt polymerization method. As increasing phosphorus contents of the phosphorus polyurethanes, we observed that the remaining char amount increased. This tendency was also confirmed in the following UL-94V test. We found that when the synthesized phosphorus polyols were applied, the resulting phosphorus polyurethanes show UL-94V0 grade at above 0.5 wt% phosphorus contents.
