    摘要: The invention relates to a process for the modification of an olefin polymer to form a coupling agent by grafting it with an unsaturated acid or acid derivative in the presence of a free-radical initiator. The process comprises stages at whicha) the olefin polymer, the unsaturated acid or acid derivative and a first free-radical initiator are heated together to a temperature at which the first free-radical initiator substantially breaks down into free radicals, andb) the reaction mixture derived from stage a) is heated together with a second free-radical initiator to a temperature at which the second free-radical initiator substantially breaks down into free radicals. By the process, olefin polymers can be modified effectively without their macromolecules degrading excessively.

    摘要: In conventional spraying methods the problem in the preparation of small carrier particles aimed for the polymerization is that the drops constituting the prestages of the particles agglomerate or form otherwise in different sizes, whereby the size distribution of the carrier particles becomes too broad. This leads due to the so-called replica phenomenon to a polymer product having also a too broad particle size distribution. In the present invention the carrier is prepared by spraying a liquid containing a carrier through a nozzle into inert gas so that its first forms small droplets, which then solidify to small carrier particles. The desired narrow particle size distribution is provided by feeding a liquid containing a carrier through a nozzle, in which or in connection with which the liquid drops by means of the standing sonic waves in the ultrasonic range into small droplets of uniform size. The droplets of uniform size solidify then into small carrier particles of equally uniform size.

    摘要: The invention relates to a method and device for feeding a mud-like catalyst mixture into a polymerization reactor. The catalyst mixture is fed from a container into a batching space of a feeder connected thereto, from which channel the catalyst mixture is further fed by batches into the polymerization reactor by the use of the pressure of a medium fed into the feeder. In accordance with the invention, after each catalyst batch fed into the polymerization reactor, the medium is substantially removed from the batching space of the feeder by leading the medium via an outlet channel into a space between two on/off valves before filling the batching space with a new catalyst batch.

    摘要: Polyolefin-vinyl polymer composites are produced by impregnating polyolefin particles with vinyl monomer and free radical polymerization initiator in the ratio of about 10-200 parts by weight of vinyl monomer and 0.01-4.0 parts by weight free radical polymerization initiator per 100 parts by weight polyolefin, the impregnation being effected by slowly mixing the components at room temperature or at an elevated temperature below the decomposition temperature of the free radical polymerization initiator. After the impregnation is completed, an aqueous suspension of the mixture is formed by adding the same to water in a ratio of about 100 parts by weight of mixture per 80-1000 parts by weight of water, after which the aqueous suspension is heated to a temperature sufficiently high to polymerize the vinyl monomer.

    摘要: A testing device for vehicle tires, especially anti-skid features situated in the vehicle tire, in which the tire to be tested is pressed against an outer circle or surface of another tire, while these two tires are rotated in opposite directions. The other tire acting as a counterpart or pair for the tire being tested is a pneumatic tire, while the tire to be tested and the other tire are disposed to be pressed against one another so that a contact surface between the two tires is substantially straight. The other tire acting as the pair or counterpart for the tire to be tested is provided with a wear surface having good wear resistance properties.

    摘要: The present invention concerns a fixed spike or a sleeve-mounted spike, fitted on a vehicle tire. The flange (12) and the body (11) of the fixed spike or the sleeve-mounted spike (20) or the flange of the rivet and the sleeve, are shaped at least in the part of the flange (12) and of the body part (11) facing the flange (12) or in the part of the flange of the rivet and the sleeve facing the flange of the rivet, in such manner that the fixed spike (10) or the sleeve-mounted spike has no detrimental sharp discontinuities (11d,12d). The rubber (14) is arranged to flow smoothly around the fixed spike (10) or around the sleeve-mounted spike, at least in the region (A) between the flange (12) and the body structure of the tire and in the region (B) of the body part (11) facing the flange (12) or in the region (A) between the rivet flange and the body structure of the tire and in the region (B) of the sleeve facing the flange, whereby forming of air pockets, and at the same time damage to the rubber, can be substantially avoided. In addition, in the region (B) of the body part (11) facing the flange (22) or in the region (B) of the sleeve facing the flange of the rivet, a force better supporting the fixed spike (10) or the sleeve-mounted spike, is at the same time obtained.
