| titleOfInvention | Neocarbyl-substituted phosphorates |
| abstract | Included is a process for the preparation of a ((neocarbyl)contrasting-halo-substituted)phosphorate comprising serially contacting (1) a phosphorus trihalide with a neocarbyl alcohol; (2) an oxirane; (3) a halogenating agent; and (4) an oxirane, under conditions sufficient to prepare the ((neocarbyl)contrasting-halo-substituted)-phosphorate. The phosphate can be very pure. Also included is a method for improving a production characteristic of flame-retardant polyurethanes. The characteristic may be selected from the group consisting of (1) processability; (2) scorch; (3) odor; (4) flame-retardant efficiency; and (5) combinations thereof. The method comprises incorporation into a polyurethane an amount effective to reduce combustibility of the foregoing phosphorate flame retardant under conditions sufficient to improve said characteristic. Also included is the flame-retardant polyurethane composition of said method. Preferably, the polyurethane is a foam, especially a flexible foam and most especially flexible slabstock foam. |
