Abstract

<PICT:0491739/III/1> The polymerization of liquid or dissolved initial materials is carried out on a moving band, the initial material being supplied to one end of the band and the polymer being removed from the other end. The band, which is preferably groove-shaped and may consist of thin steel, may be housed in a gas-tight chamber provided with a gas or vapour outlet pipe. In the apparatus shown, a housing 1 contains an endless steel band 4 mounted on rollers 2, 3 one or both of which is driven. A heating or cooling device may be provided around the band. The housing 1 is provided with inlet pipes 5, 6 for the initial materials situated adjacent one end of the band, and with a vapour outlet pipe 8. A scraper 7, preferably reciprocatable by an eccentric drive, engages the discharge end of the band. The polymer removed by the scraper passes to a kneading device 9, capable of being heated. A slide 10 enables the part of the housing 1 containing the device 9 to be cut off from the remainder of the housing in order that the polymer may be removed without interrupting the polymerization process. The treading device may be replaced by a worm conveyer which works the polymer and delivers it through orifices in the form of rods or tubes.ALSO:<PICT:0491739/IV/1> The polymerization of liquid or dissolved initial materials is carried out on a moving band, the initial material being supplied to one end of the band and the polymer being removed from the other end.

The apparatus may be employed for the polymerization of isobutylene, a mixture of liquefied isobutylene and liquefied ethylene being supplied through the pipe 5 and a solution of boron fluoride in liquefied ethylene through the pipe 6, or for the polymerization of vinyl isobutyl ether, a solution of the ether in propane being supplied through the pipe 6, and propane mixed with boron fluoride through the pipe 5.
