    Abstract: A tin electroplating solution, characterized in that it has a pH of 1.5 to 6.0 and comprises the following components: (1) 5 to 60 g/L of a tin (II) ion, (2) a complexing agent, (3) a surfactant and (4) 0.01 to 0.5 g/L of a bismuth (III) ion; and a method for the tin plating of electronic parts or the like which comprises using the tin electroplating solution are disclosed. The tin electroplating solution exhibits a soldering wettability being comparable with or superior to a conventional tin-lead alloy (solder) without the use of hazardous lead or an organic brightening agent.

    Abstract: Provided herein is a process of fractionating ferroelectric, preferably vinylidene fluoride polymers using a solvent having at least one polarizable functional group, and a precipitant. The composition of the fractionated ferroelectric polymers is selected so as to adjust the properties of a ferroelectric film made from the polymers. Films formed using the fractionated vinylidene fluoride polymers have improved properties, particularly with respect to roughness and crystal domain size, and suitability for use in data processing devices.
