Various tert-Bu and di-tert-Bu esters, N-BOC and di-N-BOC amines, metal salts of N-BOC amino acid, and glycerol-formic acid esters are potential porogens for porogen-derived membranes. Introduction of more than 20 such compounds into polysulfone or PVC films were studied. Transparency, IR spectra, changes in glass transition temperature, and DSC were used to differentiate between mol. dispersion and formation of microphases. For many of the studied additives >10% by weight can be practically molecularly dispersed in the polymers. The upper limit of porogen concentration in premembranes depends on characteristics of the polymer and of the porogen, on casting solvent composition, and on drying procedure. Metal salts of N-BOC amino acids are suitable heat-decomposable porogens. Their decomposition in premembranes proceeds in two stages, in the first of which 2C4H8 + 2CO2 are released per salt mol. The metal complex formed goes through decarboxylation at a higher temperature A heating procedure for completion of the first decomposition stage and for avoiding the second was determined This study involved multiple reactions and reactants, such as Di-tert-butyl decanedioate (cas: 143050-66-2Recommanded Product: 143050-66-2).
Di-tert-butyl decanedioate (cas: 143050-66-2) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: 143050-66-2
