  • Patent number: 5100978
    Abstract: Polyethylene and copolymers of predominant amounts of ethylene and minor amounts of comonomers which are polymerizable with ethylene are obtainable by free radical polymerization of the monomers under from 1,500 to 5,000 bar and at from 40.degree. to 250.degree. C. by means of an initiator with virtually complete exclusion of oxygen in not less than n=3 polymerization stages, by a method in which, in the first stage, the total amount of the predominant part of the monomers are subjected to polymerization using some of the initiator required, until said polymerization comes virtually to a stop, thereafter a further part of the initiator and, if required, of the monomers are added to the mixture, which has been cooled by 20.degree.-60.degree. C., and this process is repeated in the subsequent stages until the n th stage, with the proviso that the initiators used in the (n-1) th stage have a half-life temperature of from 80.degree. to 160.degree.

  • Patent number: 5097463
    Abstract: A laser-optical write and read process whereby a thermally alterable recording layer which contains liquid-crystalline compounds in homogeneous planar orientation and forms part of a multilayer, sheet-like recording material is written by means of a write laser beam with analogue or digital data in the form of thermally altered areas, whereafter the written data are read by means of a read laser beam, including: analyzing the light transmitted or reflected by the recording material, and reading the data by determining the polarization-optical contrast between the thermally altered and the unaltered areas and/or utilizing for this purpose the interference of the light rays which form from the laser lightwaves in a Gaussian intensity distribution owing to the different phase velocities of the light in the center of thermally altered areas on the one hand and their thermally unaltered surroundings on the other.
