摘要: The present invention is a method to start-up process make expandable vinyl aromatic polymer pellets comprising, a) providing pelletizer (S) containing means introduce the molten comprising agent and optionally additives, die plate having plurality of holes small diameter, typically in range 0.8 1.6 mm cutting pellets, b) (L) large 3 5 c) sending an additives until flow rate operating provided proportion optional are specifications, d) switching stream said at conditions effective produce e) recovering from f) produced step for subsequent recycling state d). In another embodiment while production troubles happen introduction expanding and/or or any equipment even needs maintenance switched one more pelletizers (L). When over, (S). diameter removed replaced by convert into capable pellets. By way example established used during other
