Phosphate-functionalized acrylic materials were synthesized by free-radical polymerizations of MMA and DMP using the BPO-DMpT initiated reaction system. The resulting products were able to react with the HEMA monomer, thus yielding polymers with a chain structure of P(MMA-co-DMP)-b-PHEMA. Remarkably, incorporating DMP and/or PHEMA into PMMA main chain rendered a copolymer with low Tg while increasing the Td intrinsic to PMMA. The enhancement of overall thermal stability of the acrylic materials is a feature of great interest for applications in bone cements and coating system additives.
