摘要： A process for increasing the molecular weight of condensation polymer comprises introducing a low molecular weight starting material to a reactor vessel, the vessel being equipped with a means for heating the material and further being equipped with a means for stirring the material, the vessel being further equipped with a means for introducing an inert gas, the vessel being further equipped with a means for removing the inert gas, the vessel being further equipped with a means for applying vacuum to the material while it is being stirred; heating the vessel either before, during, or after the introduction of the material to a temperature at which a polycondensation reaction will proceed; stirring the material during the polycondensation reaction; and during the polycondensation reaction, causing an inert gas to flow through the vessel over the surface of the material, the insert gas being at a pressure of no greater than 13 kPa (100 torr); and the rate of flow of the inert gas preferably being from 3 to 30 m/sec (10 to 100 ft./sec.), and removing the material when the molecular weight has undergone a desired increase.

摘要： The invention relates to an extruder comprising at least two conical stators and at least one rotatable rotor situated between the stators. The extruder comprises a supply conduit (3) for supplying material into the space between the stators (2), and the rotor (1) comprises at the orifice of the supply conduit (3) openings (5) via which the material to be supplied can flow to the interior of the rotor (1). The end of the supply conduit (3) and ducts formed of the openings (5) and/or grooves (7, 7a, 7b) of the rotor (1) are designed in such a way that the sum of the areas of the sections of ducts visible at the end of the supply conduit (3) remains substantially constant at each moment when the rotor (1) rotates. In such a case, the material to be supplied through the supply conduit (3) can flow evenly from the supply conduit (3) to the grooves (7, 7a, 7b) of the rotor (1) and via the openings (5) so that there will be no pumping effect in the flow of material.

摘要： The invention relates to a method for producing a thermoplastic elastomer material in the form of a mixture of one or more thermoplastics and one or more crosslinked rubbers. Said mixture contains the following constituents: one or more thermoplastics for 10-90 %, one or several non-crosslinked rubbers, a crosslinking activator, a crosslinking agent, possibly other additives. Said process involves the use of a roll system characterized by the following process steps: the thermoplastic(s) and /or the non-crosslinked rubber(s) are introduced into the roll system through the feeding opening in the absence of the crosslinking agent and are subsequently melted and dispersed with formation of a homogenous mixture; the homogenous mixture is conveyed in the roll elements at the same time as the crosslinking agent is delivered to a transition area in the roll elements; the mixture provided with the crosslinking agent is dispersed and homogenized at the same time as vulcanization at high extension rates with formation of the thermoplastic elastomer material. The calendered surface amounts to ≥ 75m2 thermoplastic elastomer per kilo in relation to the totality of roll elements. Another variation of the method is also disclosed.

摘要： The invention relates to a method for making a product to be extruded, and an extruder. The extruder comprises at least two conical stators (1, 2) and at least one conical rotor (3) placed rotatably between the stators. The extruder further comprises supply conduits (6, 7) for feeding the material to be extruded separately into the exterior and interior of the rotor (3). Each supply conduit (6, 7) is provided with a separately adjustable feeding device (9, 10) by means of which the amount of the material flow to be supplied can be adjusted. In such a case, the degree to which the space between the rotor (3) and the stator (1, 2) is filled and the amount of the heat generated by the friction can be regulated. Further, the ratio of the material flows in the different supply conduits (6, 7) determines the ratio of the thicknesses of the layers obtained. Therefore, the method and apparatus according to the invention make it possible to regulate the properties of the final product easily and in several different ways.

摘要： An extrusion apparatus and method, and a tubular product and a pipe made of several different materials. The extrusion apparatus according to the invention comprises at least one stator (1, 6, 10), at least one rotor (2, 2a, 2b), and at least one annular feed gap (3) situated between the stator (1, 6, 10) and the rotor (2, 2a, 2b). The diameter of the feed gap (3) decreases at least partly continuously in the direction of flow of the plastic material to be extruded, and its diameter also increases continuously at least at a section of its length in the aforementioned direction of flow. With such a construction, the pressure acting on the structure of the extrusion apparatus can be considerably balanced, i.e. the apparatus can be made more durable. The invention also relates to a tubular product and a pipe made of several different materials.
