Abstract

To improve the hydrophilic properties of poly(propylene carbonate) (PPC)

hydroxyl-functionalized PPC (PPC-OH) were prepared by two steps. First

PPC containing

-nitrobenzyl (ONB) protecting groups (PPC-ONB) were synthesized by terpolymerization reactions of 2-{[(2-nitrophenyl)methoxy]-methyl}oxirane (monomer

)

propylene oxide (PO)

and CO

over SalenCo

(III)

Cl/bis(triphenylphosphine)iminium chloride (PPNCl) catalyst system.

H-NMR result showed that the PPC-ONB was a random copolymer with monomer

randomly inserted. Then PPC-OH were obtained with the removal of

-nitrobenzyl (ONB) protecting groups under ultraviolet (UV) irradiation. PPC-ONB were synthesized with various feed ratios of the monomer

and different reaction time. Based on the analysis of

H-NMR

C-NMR

gel permeation chromatography (GPC)

and differential scanning calorimeter (DSC)

SalenCo

(III)

Cl catalyst performed high reactivity and high selectivity (

94%). The polycarbonate exhibited excellent regioselectivity and perfect alternating copolymerization of CO

and PO with the carbonate linkages up to 98%

and the head-to-tail linkage (HT) up to 99%. With the increase of the feed ratios of the monomer

the polymer ratio of the monomer

increased to 19.4% without sacrificing the reactive activity

while the molecular weight (

) decreased slightly owing to the better reactivity of monomer

. The glass transition temperatures (

) were in the range of 35.7 − 38.9 °C. The kinetics of deprotection by UV irradiation proved that the ONB protecting groups could be carried out efficiently within minutes. And the characterization of polymer by

H-NMR

Fourier transform infrared spectrometer (FTIR) and GPC showed that the ONB protecting groups were removed and the ―OH was observed. Meanwhile

no degradation of polymer backbone occurred. The contact angle (CA) measurement of PPC-ONB and PPC-OH displayed a difference in hydrophilia. The hydrophilia of PPC-OH has been greatly improved compared with PPC-ONB due to the increase in polarity

and the CA of PPC-OH decreased from 78.3° to 58.6° when the molar ratio of ―OH increased to 19.4%.
