Abstract:
We report the successful synthesis of hydrophilic thioester-containing polyacrylamide copolymers by the RAFT and free-radical copolymerisation of dibenzo[c,e]oxepane-5-thione with either acrylamide or N-isopropylacrylamide. These copolymers efficiently degrade in aqueous solutions of sodium hydroxide, isopropylamine, L-cysteine, and household bleach, reducing the weight-average molecular weight by up to ∼90%.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
