Abstract:

Five typical specious questions in polymer chemistry were discussed, including "the criterion of the spontaneity of a polymerization is △G < 0", "the activities of the two kind of active centers in an ideal copolymerization are the same", "ferrocenylmethyl acrylate (FMA) has a higher propagation rate constant of homopolymerization than 2-ferrocenylethyl acrylate (FEA)", "Methyl 3-(4-methylphenyl)-2-propenoate, or Methyl 4-methylcinnamate, can be homopolymerized into high polymer" and "α-cyanoacrylate cannot be free radically homopolymerized". Through raising and answering these questions, the students were encouraged to think, to doubt, to question, to explore, to acquire, and to understand under the teacher's inspiration and guidance. This helps to train the critical thinking skills, the problem conversion ability and the literature consulting awareness, to build the awareness and abilities of problem finding and problem raising, and to develop the ability to analyze and solve problems, in addition to acquire the right knowledge.

Key words: Polymer chemistry, Teaching, Critical thinking, Problem conversion ability, Literature retrieving, Awareness development
