  • Bisphosphonates vinylic monomers and polymers and uses thereof
    Patent number: 10508126
    Abstract: A compound or a polymer is claimed. A first formula can be wherein X is H, CH3, CN, phenyl, substituted phenyl, (CH2)mZ, or phenyl(CH2)mZ; T is O, N, S or NH; m equals 1 to 20; n equals 1-100; and Z is CN, NH2, Thiol, OH, or CO2H. The second formula is: wherein X is H, CH3, CN, phenyl, substituted phenyl, (CH2)mZ, or phenyl(CH2)mZ; and Z is CN, NH2, Thiol, OH, or CO2H. The third formula is wherein: R1, R2, R3, and R4 are independently: H, CH3, OH, or a halogen.
