报道了用含氮、磷协同阻燃基团的蓖麻油衍生物代替氯气内增塑PVC，即将蓖麻油衍生物接枝到PVC基体上。改性PVC的玻璃化转变温度（Tg）较低，但热稳定性降低。然而，移民被完全压制了。将含氮磷协同阻燃基团的蓖麻油衍生物与PVC基体结合，通过咔嗒反应改性PVC材料，制备出零迁移、阻燃性能增强的柔性PVC材料。
Internally plasticized PVC by replacement of chlorine with castor oil derivative containing synergistic flame retardant groups of nitrogen and phosphorus, that is, castor oil derivative grafted onto PVC matrix, is reported. Low glass transition temperature (Tg) of modified PVC was produced although thermal stability was reduced. However, the migration was completely suppressed. The combination of castor oil derivative containing synergistic flame retardant groups of nitrogen and phosphorus with PVC matrix through modifying PVC materials with click reaction prepared flexible PVC materials with zero migration and enhanced flame retardant property.
