Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania granulowanego poli((met)akrylanu metylu), który polega na tym, że od 5g do 12,5 g poli((met)akrylanu metylu), korzystnie 10 g rozpuszcza się odpowiednio w 45 cm3 do 37,5 cm3, korzystnie 40 cm3 rozpuszczalnika glimowego w temperaturze 45°C do 95°C, korzystnie 90°C, otrzymując odpowiednio roztwór polimeru o stężeniu od 10% do 25%, korzystnie 20% masowych, odparowuje monomer pod ciśnieniem 35 mbar do 80 mbar w temperaturze 45°C, poddaje granulacji mieszaninie dwóch rozpuszczalników: nieprotonowego i niepolarnego rozpuszczalnika alifatycznego od C-5 do C-8, z którym korzystnie miesza się polarny organiczny rozpuszczalnik niskocząsteczkowy od C-1 do C-3, schładza do temperatury 20°C, po czym wkrapla roztwór polimeru przy szybkości mieszania 80 rpm do 800 rpm korzystnie 250 rpm oraz intensywnością wkraplania równą od 0,2 do 5 kropli na sekundę, korzystnie 2 krople na sekundę przy czasie granulacji nie krótszym niż 10 sekund do 24 godziny, korzystnie 10 min, mieszaninę dekantuje, granulat suszy pod zmniejszonym ciśnieniem 2 mbar do 10 mbar korzystnie 6 mbar w temperaturze od 20°C do 25°C, korzystnie 20°C.The subject of the application is a method for obtaining granulated poly(methyl(meth)acrylate), which comprises dissolving from 5g to 12.5g of poly(methyl(meth)acrylate), preferably 10g, in 45cm3 to 37.5cm3, preferably 40cm3 of alumina solvent at a temperature of 45°C to 95°C, preferably 90°C, to obtain a polymer solution with a concentration of 10% to 25%, preferably 20% by weight, evaporating the monomer under a pressure of 35 mbar to 80 mbar at a temperature of 45°C, granulating a mixture of two solvents: a non-protic and non-polar aliphatic solvent from C-5 to C-8, with which a polar organic low-molecular-weight solvent from C-1 to C-3 is preferably mixed, cooling to a temperature of 20°C, and then adding the solution dropwise polymer at a stirring speed of 80 rpm to 800 rpm, preferably 250 rpm, and an instillation rate of 0.2 to 5 drops per second, preferably 2 drops per second, at a granulation time of not less than 10 seconds to 24 hours, preferably 10 minutes, the mixture is decanted, the granulate is dried under reduced pressure of 2 mbar to 10 mbar, preferably 6 mbar, at a temperature of 20°C to 25°C, preferably 20°C.
