The thermal degradation behavior of the block copolymers obtained was studied thermogravimetrically. As a typical example, TG and differential thermogravimetric (DTG) curves of the block copolymer from the poly(NMAAm)/EA system are shown in Fig. 28, together with those of poly(NMAAm) and poly(EA). The block copolymer decomposed at a higher temperature than poly(NMAAm), despite the fact that the former contains a poly(NMAAm) block. Similar behavior was observed in other copolymers. This phenomenon may be rationalized as follows. As already mentioned, the prepolymerization of NMAAm in benzene yields microspheres of poly(NMAAm)...
