Method for Forming and Continuous Orientation of the Article Containing Crystal and Semi-Crystal Thermoplastic Polymer Material/Materials, Method for Production of Laminated Tubular Article, the Article and Extrusion Device

摘要

1. Technical Result Increase in strength of article. 2. Essence When forming and continuously orienting the article, containing polymer material, the substances having the reaction in particular in the form of cross-link agent is introduced into the polymer material, after which the chemical reaction for reducing the mobility of the molecules of polymeric material is initiated. The obtained mass is dissolved in the axial or radial directions. Then, the product thus obtained is calibrated and cooled in an oriented state. The method is executed in the extrusion device. 3. Field of Application Domestic chemistry.
