Polymeric plasticizers. Preparation and characterization of a series of terminated polyesters was written by Koroly, Joseph E.;Beavers, Ellington M.. And the article was included in Industrial and Engineering Chemistry in 1953.Category: alcohols-buliding-blocks The following contents are mentioned in the article:
The general schematic structure for terminated polyesters L-G-(-A-G-)n-L, where A represents a dibasic acid, L a mono-basic acid, G a dihydric alc., and n is the number of repeating units, is the basis of preparation of a polymeric plasticizer series. The monobasic acid of the reported study is lauric; the dibasic acids are succinic, adipic, sebacic, glutaric, thiodipropionic, azelaic, and γ-methyl-γ-acetylpimelic; the glycols are 1,2-propylene, ethylene, trimethylene, 1,3-butylene, 2,2-dimethyl-1,3-propanediol, and 2-ethyl-2-butylpropanediol; and the values of n are 1-10. The rate and degree of completion of the first reaction stage, which was direct esterification, was characterized by determination of the acid number; and that of the second reaction stage, which was polymerization by trans-esterification, was characterized by melt viscosity of the reaction mixture 20 references. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Category: alcohols-buliding-blocks).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. 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.Category: alcohols-buliding-blocks
