To master polymerization process and control is a basic skill for students majored in polymer and relevant field. In this paper

a new-type teaching mode of polymerization process is introduced on the base of course teaching of "polymerization process" and production practical teaching

that is combining the "leaning" of the teaching and "observing" of the practice through simulation experiment

and then upgrading to the integrated design of switch on/off and fault handling of products production

finally forming a new four-in-one teaching mode. It has been found that the new-type teaching mode can help students to improve the abilities of practical operating control in large-scale polymerization process

integrate design in process operation plan and coordinate organization in production.
