In this thesis, the writer describes flexible and easy-to-use the way to keep an eye on the homes of thermoresponsive polyacrylamides by means of constructing novel artificial equipment for end-functionalized poly(N-isopropylacrylamide) (PNIPAM) and block copolymers of poly(N,N-diethylacrylamide) (PDEAA). The synthesis of assorted urea end-functionalized PNIPAMs was once completed by means of the atom move radical polymerization (ATRP) and the clicking response. The section transition temperature of PNIPAM in water used to be managed looking on the power of the hydrogen bonding of the urea teams brought on the chain finish of the polymer. Novel dwelling polymerization equipment for N,N-dimethylacrylamide and N,N-diethylacrylamide have been built through workforce move polymerization (GTP) utilizing a powerful Brønsted acid as a precatalyst and an amino silyl enolate as an initiator. This approach enabled the best synthesis of PDEAA and its block copolymers―namely, thermoresponsive amphiphilic block copolymers and double-hydrophilic block copolymers.
