Title: Process for preparing a polyvinyl chloride composition having improved dielectric properties
IPC: C08K3/26
Filed: 1963-11-04
Abstract: In a process for the manufacture of polyvinyl chloride compositions, lead carbonate is deposited from an aqueous dispersion on the surfaces of particles of polyvinyl chloride prepared by suspension polymerization, which particles have a rough and broken surface, and a plasticizer is then incorporated with the particles.  The lead carbonate may be neutral or basic and may be formed in situ by reaction between a water-soluble lead salt, e.g. lead acetate, and a water-soluble carbonate, e.g. ammonium or sodium carbonate.  The plasticizer may be dioctyl phthalate, adipate or sebacate.  The compositions may also comprise stabilizers, e.g. barium or cadmium laurate or tin compounds, and lubricants, e.g. sodium, calcium or lead stearate or a wax, and may be used to insulate electrical conductors. In examples dispersions of vinyl chloride suspension polymers containing polyvinyl alcohol and lead acetate are treated with (1) ammonium carbonate and (2) sodium carbonate, and the dried products compounded with dioctyl phthalate, basic lead carbonate and dibasic lead stearate.

G4] In a continuously rotating type-cylinder machine a hammer is provided for each character position and they are mounted on a carrier so that only one hammer at a time is in effective position. As shown in Fig. 3 the hammers h 1  are mounted! on a continuously rotating disc H and at the end of arms which are angularly spaced. andi are of progressively increasing lengths so that the hammers form a helical array and each one extends to its own column of character on a type drum T. In this embodiment the disc is geared so that its axis is at right angles to that of the type drum T and it rotates once for each angular characterpitch on. the cylinder; i.e. as many revolutions as there are characters (or blanks) spaced manually on the drum T. This applies to a. system of printing where all. characters of a like nature in the line are printed at a first step, the type drum is advanced to the next character when all positions in the line requiring this character are printed, and so on until the line is complete. The gearing could be arranged so that a complete revolution of the drum is made for each letterspace position with the appropriate timing of the operation of the hammer in that position. In an embodiment described in Fig. 2 (not shown) the hammers h 1 , h 2  &c. are arranged on small springs f at the periphery of the drum in a helical array. An operating electromagnet is located inside the drum. The printing can be effected by the two methods described in respect to the embodiment employing hammers on a disc. The paper web P, Fig. 1, is advanced by an electromagnet Mv driving rollers R 1 , R 2 . The operation of the electrical circuits is described in Divisions G4-G6.
