Thermodynamic properties of polymethyl methacrylate and methyl methacrylate

Journal of Polymer Science Part A: General Papers, 1963
AbstractFrom 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.

Copolymerization of N-vinylindole with methyl methacrylate and methacrylic acid

Polymer Science U.S.S.R., 1967
TH~ production of new copolymers enabling the properties of previously known homopolymers to be modified has recently been a major aim in the study of polymeric compounds. Information is available in the literature regarding the copolymerization of certain N-vinyl monomers: N-vinylearbazole [1], N-vinyl-laetam [2] and N-vinylphthalimide [3]. However no

Aqueous polymerization of methyl methacrylate. III

Journal of Polymer Science: Polymer Chemistry Edition, 1983
AbstractThe aqueous polymerization of methyl methacrylate (MMA) initiated by potassium persulfate (I)‐thiomalic acid (TMA) redox couple has been studied at 30 ± 0.2°C under nitrogen atmosphere. The rate of polymerization is given by up to 20.0 mmol/L TMA concentration, where x = 0.52 for the I concentration 0.6–10 mmol/L and x = 0.27 for higher I ...

Photodegradation of blends of poly(methyl methacrylate) and poly(styrene-co-methyl methacrylate)

Polymer Degradation and Stability, 1992
Abstract The photodegradation of blends of poly(methyl methacrylate) (PMMA) and poly(styrene-co-methyl methacrylate) (poly(St-co-MMA)) was studied using ultraviolet and Fourier-transform infrared (FTIR) spectroscopy and viscosity measurements. PMMA-poly(St-co-MMA) blends give macroscopically transparent films. The rate of formation of the oxygenated

Compatibilization of blends of polybutadiene and poly(methyl methacrylate) with poly(butadiene-block-methyl methacrylate)

Journal of Polymer Science Part B: Polymer Physics, 1998
Compatibilization of blends of polybutadiene and poly(methyl methacrylate) with butadiene-methyl methacrylate diblock copolymers has been investigated by transmission electron microscopy. When the diblock copolymers are added to the blends, the size of PB particles decreases and their size distribution gets narrower.
