Reductively degradable hyperbranched polymethacrylates with multiple peripheral alkyl bromide groups were synthesized by the azobis(2-isobutyronitrile)-initiated copolymerization of diethylene glycol methyl ether methacrylate or oligo(ethylene oxide) methyl ether methacrylate with the disulfide-containing crosslinker bis(2-methacryloyloxyethyl)disulfide (2.5–10.0 mol-% relative to the monomer) in the presence of carbon tetrabromide (10–40-fold excess relative to the radical initiator) as efficient chain transfer agent. The alkyl bromide groups initiated the atom-transfer radical polymerization of methyl methacrylate, and star copolymers with hyperbranched disulfide-containing cores were formed. Both the macroinitiators and the star copolymers derived from them were degraded in reducing environment.

Differential scanning calorimetry (DSC) measurement is used to investigate the nonisothermal crystallization behavior of poly (vinylidene fluoride) (PVDF)/polysulfone (PSF)/diethylene glycol dibenzoate (DEDB)/dibutyl phthalate (DBP) system via solid-liquid (S-L) phase separation during a thermally induced phase separation process. The effect of benzene ring in PSF on PVDF crystallization for PVDF/PSF/DEDB/DBP system is investigated. It is found that the Ozawa model can describe nonisothermal crystallization behavior of PVDF/PSF/DEDB/DBP system in a certain crystallization temperature range. Jeziorny method indicates that the secondary crystallization of PVDF exists in the process of nonisothermal crystallization and is enhanced by the increase of cooling rate.
