Copolymerization of methyl methacrylate and urethane methacrylate—II
European Polymer Journal, 1992Abstract A methacrylate monomer (MAUN) having a pendant urethane linkage was prepared by reacting tolylene diisocyanate (TDI), 2-naphthol and 2-hydroxyethyl methacrylate (HEMA). Photopolymerization in the absence of photosensitizer in the temperature range 32 to 62° was investigated using differential photocalorimetry.

Thermodynamic properties of polymethyl methacrylate and methyl methacrylate
Journal of Polymer Science Part A: General Papers, 1963AbstractFrom published data the entropy, enthalpy, and Gibbs free energy of polymethyl methacrylate (PMMA) have been calculated over the temperature range 0–260°K. These functions have also been calculated for methyl methacrylate over the range 0–210°K. The entropy of polymerization at 210°K. was found to be 9.63 cal./mole°K.

Polyurethane or Methacrylate For Arthroplasty
JAMA: The Journal of the American Medical Association, 1972To the Editor.— I have just read, with considerable interest and dismay, Dr. Mandarino's reply (219:512, 1972) to Dr. Eftekhar's article on low-friction arthroplasty (218:705, 1971). Dr. Mandarino suggests, if I interpret his remarks properly, that we reconsider the use of polyurethane foam (Ostamer) as a substitute for methylmethacrylate as the ...

Copolymerization and copolymers of styrene with dodecyl methacrylate and octadecyl methacrylate
1999Styrene (St) was copolymerized with dodecyl methacrylate (DDMA) or octadecyl methacrylate (ODMA) in toluene using AIBN as free radical iinitiator over a wide composition and conversion ranges. The copolymer composition was determined from H-NMP spectra. The copolymerization reactivity ratios were determined. The Q and E values were also calculated. The
