Diphenylsulfone (DPSO2) was found to react with an equimolar amount of potassium in tetrahydrofuran (THF), dimethoxyethane (DME), or diglyme (DG) at reflux or an elevated temperature to yield a reddish-black solution, giving an electron spin resonance (ESR) signal. The signal was attributed ...

Polymerization of 2-(Perfluoroalkyl)ethanyl Vinyl Sulfones 2-(Perfluoroalkyl)ethanyl vinyl sulfone (1.00 g, 1.86 mmole, RF =0.78% C6 F13, 95.6% C8 F17 and 0.84% C10 F21) and 0.100 g (0.61 mmole) of azo-bis-2-methylpropionitrile were heated under nitrogen in 20 ml of benzene while ...
Vinyl ester was prepared via methacrylation of Epon 828™. 525.7 g Epon 828™ resin was reacted with 243.5 g methacrylaic acid. AMC-2 was used as a catalyst for the reaction and to prevent epoxy homopolymerization in the amount of 7.6 g (equivalent to 1 wt %). The reaction was...
On the other hand, less attention has been paid to ionic graft polymerization. Sasson and Zilkha reported on grafting formaldehyde onto potassium-metallated PVA (Sasson and Zilkha, 1969). Galin studied grafting of AN and propane sulfone onto sodium-metallated PVA (Galin, 1971). We used the ...
Synthesis of a Poly(vinyl alcohol)Based Graft Copolymer Having Poly(e-caprolactone) Side Chains by Solution Polymerization Poly(vinyl alcohol)- graft -poly( ε -caprolactone) (PVA-g-PCL) was synthesized by ring-opening polymerization of ε -caprolactone with poly(vinyl alcohol)... K Aoi,H Aoi...
%, the urethane exotherm diluted by the heat sink effect of the monomer mass prevents the temperature of the formulation from reaching the necessary temperature of about 80° C for substantially simultaneous monomer polymerization and polyurethane formation to take place. As a consequence, the common...
A vinyl polymer polyol is prepared by the free radical initiated polymerization of vinyl monomers using partially alkoxylated polyoxyalkyleneamines as the dispersing media. The vinyl polymer polyols o
