<p>OF THE DfSCLOSUREPROCESS POP PRODUCING POLYMER COMPOSITIONThe present invention 15 directed. to provide a process for produci,- a polymer composition which is able to more efficiently prodiice the polymer composition with high qualitA process for producing a polymer composition conducts a first polymerization sU(1), by supp:L),(.inc) a flIW Mat e.r al monomer and a polypriaation initiator to a first reactor10 of a complete mixing type (10) throuph its supply port (11a) to be subjected to continuous polymerization under an adiabatic condition in the first rebotor (10), anb taking a resultant intermediate composition from an effluent Port (nb) located at a top of the first :reactor (10) ; and a secno, polymerization step hy supplyinp the intermediate compobition to a second reactor of a complete mixing type,- its supply port (21a) to be fuxther subjected to continuous polymerization under an adiabatic condition in the second reactor (20), and taking a resultant polymer20 composition from an effluent port (211:) located at a top of The second reactor (20) wherein the first polymer' zat ion step is conAucted at a temperature from. 125 to 170(C, andsecond polymerization step is conducted at a temperature from 130 to NW°.</p> |
