NIPAm-Based Modification of Poly(L-Lysine): A pH-Dependent LCST-Type Thermo-Responsive Biodegradable Polymer

Polymers, 2022
Polylysine is a biocompatible, biodegradable, water soluble polypeptide. Thanks to the pendant primary amines it bears, it is susceptible to modification reactions.

Design of an LCST–UCST-Like Thermoresponsive Zwitterionic Copolymer

Langmuir, 2021
Thermoresponsive polymers that possess both UCST- and LCST-like behaviors have generally been designed using diblock copolymers that are mostly composed of an LCST-like polymer and a UCST polymer. Herein, we prepared an LCST-UCST-type polymer composed of UCST-like thermoresponsive zwitterionic sulfabetaine methacrylate and nonthermoresponsive PEG ...

Effects of stereochemistry and copolymerization on the LCST of PNIPAm

The Journal of Chemical Physics, 2017
Poly(N-isopropylacrylamide) (PNIPAm) is a smart polymer that presents a lower critical transition temperature (LCST) of 305 K. Interestingly, this transition point falls within the range of the human body temperature, making PNIPAm a highly suitable candidate for bio-medical applications.

Thermo‐Responsive Polyoxazolines with Widely Tuneable LCST

Macromolecular Bioscience, 2009
AbstractThe “click” modification of statistical poly[2‐(isopropyl/3‐butenyl)‐2‐oxazoline] copolymers with ω‐functionalized thiols can be used to generate a toolbox of thermo‐responsive polymers. The cloud points of the polymers can be finely tuned over a wide range as a function of composition and hydrophilicity of the side chain (hydrocarbon, alcohol,

A Novel Functional Polymer with Tunable LCST

Macromolecules, 2008
Poly(N-[(2,2-dimethyl-1,3-dioxolane)methyl]acrylamide) (PDMDOMA), a novel thermo-responsive polymer containing pendant dioxolane groups was synthesized via atom transfer radical polymerization (ATRP). Water soluble PDMDOMAs with controlled molecular weight and narrow molecular weight distribution were obtained.

LCST–UCST-Based Copolymerizations

2011
It was shown in Chap. 3 that a polymerization system can start as a conventional precipitation system and end as an FRRPP system, especially if the phase diagram exhibits an hourglass-shaped phase envelope at relatively high polymer molecular weight. This sets up the arguments for other types of shifts from UCST- and LCST-based chain polymerizations ...
