Abstract: Upper critical solution temperature (UCST)-type thermoresponsive behavior of poly(ethylene glycol)-poly(acrylic acid) (PEG-PAA) and poly(poly(ethylene glycol) methacrylate)-poly(acrylic acid) (PPEGMA-PAA) interpolymer complexes has been observed in isopropanol. For these investigations, PPEGMA and PAA with various average molecular… read more here.

DOI: 10.1002/marc.201800640
Abstract: Polymethacrylamide copolymers with hydrophobic N-substituted acrylamides, such as N-cyclohexylacrylamide and N-tert-butylacrylamide, are rare examples of polymers showing composition-dependent thermoresponsive behavior in water. They show unexpected behavior different from the conventional copolymers of a thermoresponsive polymer… read more here.

Abstract: A series of glycopolypeptides with constant main-chain lengths and bearing various mannose pendants and 3-methyl-1,2,3-triazolium linkages were synthesized by N-alkylation, ion-exchange reaction, and subsequent deprotection. 1H NMR and FTIR analysis verified their molecular structures. Their… read more here.

DOI: 10.1021/acs.biomac.2c00694
Abstract: We have reported that ureido polymers exhibit upper critical solution temperature (UCST)-type phase behavior in solution, which is the opposite of lower critical solution temperature (LCST)-type behavior. Furthermore, UCST-type ureido polymers undergo liquid-liquid phase separation… read more here.

DOI: 10.1021/acsmacrolett.2c00021
Abstract: Formation of aqueous-core polymer capsules exhibiting an upper critical solution temperature (UCST) was achieved using surfactant-polymer interfacial complexation in water-in-oil inverse emulsions. In fluorinated oil, Coulombic interactions between Krytox, an anionic oil-soluble surfactant, and a… read more here.

DOI: 10.1021/acsmacrolett.2c00731
Abstract: Embolization is often used to block blood supply for controlling the growth of fibroids and malignant tumors, but limited by embolic agents lacking spontaneous targeting and post-treatment removal. So we first adopted nonionic poly(acrylamide-co-acrylonitrile) with… read more here.
