Linear and Cross-linked UCST-Type Polymers : Synthesis and Properties
… with upper critical solution temperature (UCST)-type thermoresponsivity are required. To have a better understanding of UCST behavior, this dissertation deals with the synthesis of polymers, that show UCST-type thermoresponsivity in water or in electrolytes, with different architectures and …

Syntax of Phase Transition Peptide Polymers with LCST and UCST Behavior
… or below an upper critical solution temperature (UCST). We show that this syntax ranges from phase transition polymers composed of simple repeats of a few amino acids to polymers whose syntax resembles the complex sequence of peptide drugs and protein domains that exhibit dual levels of function, …

Twofold switchable block copolymers based on new polyzwitterions
… exhibiting upper critical solution temperatures (UCST). Phase transition temperatures depend notably on the molar mass and polymer concentration, and are much higher in D2O than in H2O. Also, the phase transition temperatures are effectively modulated by the addition of salts. The individual …

Study of the miscibility, crystallization and morphology in poly(propylene) based blends and copolymers
… shows a upper critical solution temperature (UCST) behavior. The UCST behavior is consistent with predictions by the group contribution method. Miscibility behavior of high molecular weight isotactic poly(propylene) (it-PP) and isotactic poly(1-butene) (it-P1B) blend is investigated by a …

Characterizing Multivalent Interactions Between Folded Protein Domains and Intrinsically Disordered Regions or Peptide Substrates
… exhibits upper critical solution temperature (UCST) phase transition behavior; the protein condenses into liquid-like droplets at low temperature and returns to one soluble phase at high temperature. In contrast, UBQLN2 exhibits upper and lower critical solution temperature (UCST+LCST) phase …

Self-assembly and selective swelling in Lamellar block copolymer photonic gels
… pair has an upper critical solution temperature (UCST) and the photonic gel's structural color red-shifts at high temperature. The temperature dependence can be tuned by the molecular weight of the PS-P2VP. Next we show that the PS-P2VP photonic gels are also responsive to the composition of …

Star-shaped Polyelectrolytes
… of a miscibility gap at low temperatures (UCST behavior). In salt-free solutions the electrostatic stabilization is especially pronounced for polymers with high arm numbers (having higher charge density). No macroscopic demixing was observed for polymers with more than 9 arms.

Synthesis and characterization of platinum(II) loaded thermosensitive poly(vinyl ether)s and investigations into their potential as UV-triggerable hydrosilylation catalysts
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2025-12-01

Phase Behavior and Phase Separation Kinetics in Polymer Solutions under High Pressure
… shifted to upper critical solution temperature (UCST)-type at higher CO2 levels along with an increase in the miscibility pressures. In contrast to the PE system, this system was found to display multiple miscibility windows. A "U"-shaped phase boundary in 92 % THF + 8 % CO2 mixture was observed …
