The cryopolymerization and formation of a macroporous poly(N-isopropylacrylamide) (PNIPA)/clay cryogel were investigated. The mechanism of the cryopolymerization and cryogel formation was elucidated. Two processes, cryostructuration and cryopolymeriz

FTIR spectroscopy and quantum chemical calculations have been used to explore the system of high-molecular mass pair of miscible polymers poly( N -methyldodecano-12-lactam) (PMDL) and poly(4-vinylphenol) (PVPh) in tetrahydrofuran (THF) that is known

Poly(N-methyldodecano-12-lactam) (PMDL) is miscible with poly(4-vinylphenol) (PVPh). In the system PMDL + PVPh + tetrahydrofuran containing low-molar-mass polymer pair, this miscible blend is soluble in the solvent. In this work, it has been found th

The addition of layered silicates can significantly affect the phase behaviour of both immiscible thermoplastic blends and partially miscible thermoset systems that undergo reaction-induced phase separation (RIPS) during curing. This study focuses on
