The present applications of polymers are expanding to the most parts of industry and therefore new possibilities of production are explored. The research explores possibility to produce thick homogenous sheets of isotactic polypropylene. There are two the most useful technologies to produce polymers: injection moulding and compression moulding. The injection moulding can make products with maximum 6 mm thick, so when you need bigger thickness, you must use compression moulding. The modified Browns method is usually used. No one before us correlate this method of producing of iPP with supermolecular structure. Results show inhomogeneous structure iPP. Our work is concentrated on eliminating of this problem and on finding of the optimal production conditions.
