Title: Improving the Uniformity in Thickness of Polyamide Films
Inventor: CRAWFORD LLOYD WILLIAM
IPC: B29C71/00
Filed: 1967-10-18
Abstract: 1,150,790. Improving the uniformity in thickness of polyimide films. E. I. DU PONT DE NEMOURS & CO. 18 Oct., 1967 [19 Oct., 1966], No. 47450/67. Heading B5B. The uniformity of the thickness of polyimide films in the transverse direction is improved by determining the transverse thickness profile of the film as it leaves the zone in which it has been dried and thereby detecting the distances from an edge of the film of any longitudinal lanes of the film which are thinner than desired and increasing the thickness of these lanes in the succeeding film emerging from the drying zone by selectively heating the corresponding longitudinal lanes of the film before it enters the drying zone or while it is passing through the drying zone, the film at that stage being in the form of a " poly-(imide precursor/imide) gel film " formed by casting into film form a solution of the precursor in a volatile solvent, partially evaporating off the solvent and partially converting the precursor into the imide. The expression " poly-(imide precursor/imide) is defined as meaning a polymer consisting of both imide precursor and imide units in the range of molar ratios of about 5 : 95 and 95 : 5. The term " gel film " is defined as meaning a thin sheet of the polymeric material which is self-supporting but which is laden with the volatile solvent in which the material was dissolved prior to the formation of the film by casting to such an extent that the polymeric material is in a swollen gel condition. The polymeric material of the gel film may be a poly-(amide-acid/imide) or a poly-(amide-ester/ imide). The transverse thickness profile of the polyimide film as it leaves the drying zone may be determined manually, but is preferably determined automatically by known sensing means which is joined through an automatic controller to a selective heating system located at a position in advance of the drying zone. The heating system may comprise an air duct having a narrow discharge aperture extending over the width of the gel film and provided with a series of individually controlled electric heaters adapted to heat narrow streams of air passing over them. Alternatively, a row of long narrow radiant heaters parallel with its length may be positioned over the film. In another alternative hot air at a constant temperature is supplied to a duct positioned transversely above the film and provided with a row of valves each controlling the rate of hot air flow to an individual lane of the film. The gel film is preferably heated in a first stage at 50 to 250 C. to sharply reduce its solvent content and partially imidize the precursor, followed by a second stage heating at 250 to 450 C. to remove the remaining volatiles and complete imidization. In two stage heating the uniformity of film thickness across the film is monitored after the film leaves the second stage heating zone and the heat input to selected lanes increased either before or during the passage of the film through the second stage heating zone.
