Abstract
Procedeul de obtinere a unui copolimer acrilic sub forma de perle, se supune reactiei de polimerizare în suspensie metacrilatul de metil cu acrilatul de butil în prezenta de benzen sau dicloretan drept solvent inert si a unei cantitati de 1,6% fata de monomer stabilizator de suspensie si 0,7% initiator de polimerizare, la un raport de faze monomer: apa de 1:2,3 la temperatura de 75 degree C care se mentine pîna cînd reactia devine exoterma, presiunea se reduce sub 0,2 at, si se mareste agitarea, iar temperatura creste brusc la 95 degree C avînd loc evaporarea solventului inert din interiorul perlei de copolimer.
