FIELD: chemistry.
SUBSTANCE: moulding method involves heating thermoplastic material higher than melting point, forcing the obtained melt through a die at 10-100°C higher than melting point of the thermoplastic material and cooling the product to temperature lower than melting point. The composition of thermoplastic material includes a thermoplastic polymer and a complex additive for improving moulding. The complex additive used is a reactive composition containing at least one polyether polyol and at least one thickening component selected from a group comprising polybasic organic acids, anhydrides of polybasic organic acids, fatty acids containing 8-18 carbon atoms, as well as mixtures thereof.
EFFECT: method cuts on induction time, increases rate of flawless moulding thermoplastic material, reduces power consumption and moulding temperature, lowers pressure in the equipment when moulding high molecular weight polymers, simplifies and lowers the cost of moulding articles from thermoplastic polymer materials.
