Abstract:
PCT No. PCT/US90/03394 Sec. 371 Date Dec. 12, 1991 Sec. 102(e) Date Dec. 12, 1991 PCT Filed Jun. 18, 1990 PCT Pub. No. WO90/15706 PCT Pub. Date Dec. 27, 1990.A flat and nearly mechanically isotropic liquid crystal polymer film (38) can be formed by laminating two continuous biaxially oriented films. A laminate is produced having two thin outer surface portions which are oriented in one direction, and a relatively thick inner portion oriented in a transverse direction. The film may also be formed by passing a polymer through a set of three tubular rotors (30) which are concentric and having surfaces which are concentric and define inner and outer annular polymer flow channels (33, 35) between them. These rotors may rotate in the same or opposite directions. Another way to make the film is with a slit-type die (90) through which a polymer flows in one direction, while a moving band (91) passes continuously in a transverse direction. These ordered-polymer films are useful, for example, in the production of printed circuit boards.
