Notes:
The automatic endless belt polymer fractionator utilizes a continuous application and multistage extraction technique. A thin coating of polymer deposited on a slowly moving endless belt which passes through a series of solvent-nonsolvent mixtures of increasing solvent strength is fractionally dissolved. Discussion includes the description of the construction of the apparatus, details and results of fractionations of Neoprene W and polytetramethylene ether glycol, fractionation techniques and subsequent work-up of the fractions, “large scale” preparative fractionations, and general performance characteristics.
