TL;DR: In this paper, the solubility and precipitation properties of medical-grade stereocopolymers were investigated, and the results showed that poly(L,D-lactide) was highly dependent on the L/D ratio of the copolymer.
Abstract: In this study, the solubility and precipitation properties of medical-grade stereocopolymers were investigated. The solubility of the polymers was tested with eight different organic solvents and four nonsolvents. The solubility of poly(L,D-lactide) stereocopolymers was highly dependent on the L/D ratio of the copolymer. The phase-separation ability was tested by cloud-point titration with a solvent and a nonsolvent. The solvent was in all cases dichloromethane, and the nonsolvents were n-hexane, methanol, ethanol, and isopropyl alcohol. The results showed that n-hexane was the most efficient nonsolvent. Methanol and ethanol showed quite similar precipitation properties. Isopropyl alcohol was the least efficient nonsolvent of those studied. Also, the L/D ratio of the copolymer had an effect on the precipitation properties. The precipitation happened most easily when the L content was high. The molecular weight of the copolymer had only a slight effect on the phase separation. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

TL;DR: In this article, electron-withdrawing substituents are shown to increase the chain length of free-radical hydro-dediazoniation reactions, but the actual reaction step causing the substituent effect depends on the relative rates of propagation and termination reactions.
Abstract: Electron-withdrawing substituents are shown to increase the chain length of free-radical hydro-dediazoniation reactions, but the actual reaction step causing the substituent effect depends on the relative rates of propagation and termination reactions. With benzyl alcohol as reducing agent the rate of the slow propagation step is increased, while with isopropyl alcohol the rate of the termination step is decreased. Rate constants for some reactions of radicals with diazonium ions are reported, and the nature of some of these reactions and their implication for an understanding of the homolysis of aromatic diazo compounds are discussed.

Abstract: The invention relates to a sprayable surface disinfectant based on lower aliphatic alcohols and anionic surfactants as well as on conventional additives such as corrosion inhibitors, dyes and fragrances, which comprises a combination of (a) 20 to 35% by weight of a mixture of ethyl alcohol and isopropyl alcohol in a weight ratio of 1:2 to 2:1, (b) 0.05 to 0.5% by weight of a mixture of anionic surfactants comprising (b-1) 0.04 to 0.4% by weight of a primary or secondary alkane sulfonate or alkyl sulfate having 10 to 18 carbon atoms in the alkyl radical, and (b-2) 0.01 to 0.1% by weight of an alkyl ether sulfate having 10 to 14 carbon atoms in the alkyl radical in the form of the sodium, magnesium, monoethanolammonium or triethanolammonium salt: (c) an acidifying agent to adjust the pH to 2 - 6 or an alkalizing agent to adjust the pH to 8 - 12: whilst (d) the remainder is water, the weight ratio of alkane sulfonates or alkyl sulfates (b-1) to alkyl ether sulfates (b-2) being within the range of 10:1 to 2:1, and the weight ratio of the total alcohol content (a) to the total surfactant content (b) being within the range of 300:1 to 50:1.
