简介
Thermo‐responsive monomers were designed to contain a Diels‐Alder (DA) adduct such that cyclo‐reversion would yield either the maleimide or the furan unit attached to the polymer chain. These thermally responsive monomers were then copolymerized with N‐isopropylacrylamide (NIPAM) via reversible addition‐fragmentation chain‐transfer (RAFT) polymerization to yield linear gradient‐copolymer structures as a comparison to existing nanogel/starlike systems to understand how polymer topology and composition influence solution‐state properties. Using UV–Vis spectroscopy, it was determined that solution‐state properties were thermally dependent and influenced by a number of variables such as comonomer feed ratio, polymer chain end functionality, and polymer backbone length and composition. Manipulation of the feed ratio allowed for control over the cloud point, including the breadth and location of …
