TL;DR: In this article, the authors used Fourier transform infrared spectroscopy (FTI) to study the elimination process of polyvinyl acetate and found that the activation energy for the initial step was 190kJ −1, while that for the additional process was 130kJ−1.

TL;DR: In this article, the effects of silica nanoparticles on viscosity and alcoholysis of polyvinyl alcohol/silica nanocomposites (PVA-SNs) were studied by a ubbelohode capillary viscometer and the back titration method.

TL;DR: In this article, a 2-cyanoacrylate ester copolymer and a plasticizer were used to reduce the adhesion to skin, and the copolymers were chosen based on their ability to form strong skin bonds for at least 30 seconds.
Abstract: A cyanoacrylate-based adhesive composition comprises 55-92% by weight of a 2-cyanoacrylate ester, preferably the ethyl ester, from 40-30% by weight of a vinyl chloride/vinyl acetate copolymer and not more than 25% by weight of a plasticizer (the plasticizer may be omitted entirely). The copolymer is preferably a vinyl chloride/vinyl acetate/maleic acid terpolymer. The adhesive compositions have greatly reduced adhesion to skin, not forming strong skin bonds for at least 30 seconds, in contrast to conventional cyanoacrylate adhesive compositions which form, within in about one second bonds strong enough to tear skin.

TL;DR: In this paper, a series of different monomers, including acrylamides, acrylates, and vinyl acetate, were polymerized to high conversions at temperatures between 70 and 100 °C using various initiators, solvents, and RAFT agents.

TL;DR: In this article, the effect of the composition of the initiating system and its aging is described, as well as its effect on the aging of the AL(iBu)3:DPy:TEMPO system.
Abstract: : Synthesis of well-defined poly(vinyl acetate) in 'living' radical polymerization is reported. Straight lines in semilogarithmic plots up to >90% conversion indicate internal first order in monomer and a constant concentration of growing species. Molecular weights increase linearly with conversion. The initiating system might involve persistent radicals formed by the ternary complexes of organoaluminum compounds with Lewis bases and stable radicals. This article focuses on Al(iBu)3:DPy:TEMPO system. The effect of the composition of the initiating system and its aging is described.
