57 kDa PS; 25 kDa PMMA; m ~494; n ~520 PS Mn = 57 ± 6 kg/mol PMMA Mn = 25 ± 3 kg/mol PDI of the overall block copolymer <1.2 PS molecular weight verified by SEC (taking an aliquot from the reaction mixture) and the PMMA molecular weight by NMR spectroscopy. The overall block copolymer molecular weight distribution would be determined by SEC.
The purpose of this study was to determine the strength and stiffness of osteoporotic vertebral bodies (VBs) subjected to compression fractures and subsequently treated with bipedicular injections of various polymethylmethacrylate cements. Ten spines were harvested from nonembalmed female cadavers (age

The solubility and phase behavior of poly(benzyl methacrylate) (PBzMA) and poly(styrene-co-methyl methacrylate) (P(St-co-MMA)) in a hydrophobic ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethane sulfone)imide ([C(2)mim][NTf(2)]), have been explored as a function of temperature. Although both polymers have solvatophobic phenyl groups and solvatophilic methacrylate
