抄録
Poly(4-acetoxystyrene)(PpAS), poly(4-acetoxy-3-methoxystyrene) (PAMS), poly(4-acetoxy-3,5-dimethoxystyrene) (PADMS), poly(4-hydroxystyrene) (PpHS), poly(4-hydroxy-3-methoxystyrene) (PHMS), poly(4-hydroxy-3,5-dimethoxystyrene) (PHDMS) and partially hydrolyzed acetate polymers were prepared. The effects of hydrogen bonding on the glass transition temperature (Tg) and heat capacity (Cp) of the above polymers were studied by differential scanning calorimetry (DSC). The glass transition temperatures of partially hydrolyzed PpAS and PAMS increased with the degree of hydrolysis. However, in the case of partially hydrolyzed PADMS, initially Tg increased with the degree of hydrolysis and then decreased with increasing hydrolysis. Thermal analysis of water sorbed on the polymers showed that the bound water content of PHDMS was larger than that of PpHS and PHMS. Taking the bound water content as an indication of the hydrogen bonds of each polymer, it was ascertained that the molecular motion related to hydrogen bonding was effected by the chemical structure of each polymer.
