Hyperbranched polysiloxane is a new type of hyperbranched polymer
which has the advantages of hyperbranched polymer and siloxane
thus it is a typical case in the teaching of polymer chemistry. This paper takes hyperbranched polysiloxane as the teaching object
discusses monomer selection
raw material ratio
polymerization process control and other aspects
and focuses on gradual polymerization
polycondensation reaction
gel point prediction and other related knowledge points. On this basis
the relationship between the structure and properties of polymers and the preparation method of novel hyperbranched polymers are extended. Through course design
students are organized to study this course by combining online preview
traditional teaching
classroom discussion and offline learning. Furthermore
the students' learning interest and subjective initiative are stimulated. The teaching effect and teaching quality are also discussed and explored.
