Method for obtaining on industrial scale of polyethers or polythioethers, with the star-shaped structure and their application

摘要

the subject of the invention is a method for scale industrial polieteru00f3w or politioeteru00f3w, construction of the starlight, with increased molecular weight and reduced viscosity in relation to polieteru00f3w linear propylene oxide and ethyleneby anion polymerization and their use as additives to commercially available polymers trading (cap) inactive or poorly active optically, beneficial to poly (methyl methacrylate), polystyrene or polycarbonate.the way is that the reactor filled with gas inertnym, at a temperature of from 15 to 36 degrees is anionic initiator in the form of wodorku potassium in suspension in mineral oil, an organic solvent from the group of eterowcu00f3w cyclic ligand and glycidol.the cyclic ligand and glycidol is added in a suitable organic solvent solution and dosing speed shall be subject temperature, which may not exceed the boiling temperature of the solvent used.subsequently, the mixed rate of necessary and sufficient to obtain a homogeneous suspension, after which the alkilenu oxide of general formula 1, and after having exhausted the monomer alkoholanowe end groups is performed in the hydroxyl groups by task mixture solvent but inorganic to achieve alkoholanowych end groups or wymieniaczem ion.in ru00f3wnomolowej quantities in relation to the resulting alkoholanowych active centres.
