The waterborne polyester was synthesized by melt polycondensation of secondary polyol, tertiary alc. and polybasic acid. The waterborne polyester-amino drying paint was prepared Effects of molar ratio of hydroxyl to carboxyl groups, 1, 4-cyclohexanedicarboxylic acid and trimethylolpropane dosages and cosolvent on the properties of water-based resins and coatings were investigated by viscosity and pH testings, gel chromatog. and IR spectroscopy anal. and determination of coating properties. The results showed that the resins and coatings had optimal performance as the conditions as followed: molar ratio of hydroxy to carboxyl 1.1:1, 1, 4-cyclohexane dicarboxylic acid(based on the molar of total acid) dosage of 6%, trimethylolpropane(based on the molar of total alc.) dosage of 12% and glycol monobutyl ether used as cosolvent. The coatings had good water resistance (boiling water, 2 h), storage stability (40°C, 14 d)and solvent resistance. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4HPLC of Formula: 115-84-4).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.HPLC of Formula: 115-84-4
