This study investigated the thermal properties of ester-type easy cationic dyeable poly(ethylene terephthalate) (ECDP) polymers using differential scanning calorimetry (DSC), therogravimetric analysis (TGA). The mass ratios of 5-sodium sulfo bis(-hydroxyethyl) isophthalate(SIPE) for ECDP polymers were 2.8%, 5.5%, 6.8%, respectively. The fourth monomers were diethylene glycol adipate (DGA), diethylene glycol succinate (DGS) and diethylene glycol subacate (DES) with different contents. The results suggested that the Tg of ester-type ECDP decreased with the increasing the molecule weight of the fourth monomer at fixed SIPE and fourth monomer contents. The Tch of ECDP polymer to be lower than that of the CDP polymer with the same SIPE content. And it decreased as SIPE and fourth monomer contents increased, it also decreased with the increasing of the molecule weight of the fourth monomer given the same SIPE content. The effect of the ester-type soft segments reduced the Tm of ECDP. The thermal stability of ECDP polymer was less than PET and CDP polymers, and it decreased with increasing SIPE content, but increased with the ester-type fourth monomer content increasing.

Abstract Alkanolamines, in the absence of water, are converted to the amide ester or triacetate with acetic anhydride-pyridine mixture. The amide ester or triacetate of the alkanolamine is determined by GLC on a column containing diethylene glycol succinate on Chromosorb G. Procedures for determining alkanolamines in various hair sprays are described; recoveries by the proposed procedure were satisfactory. The method developed was applied to the following 4 alkanolamines: 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, and triisopropanolamine.
