The ability of microbally produced poly(gamma,d-glutamic acid) to form stable polyelectrolyte-opposite charged surfactant complexes was investigated. A sonicated sample of polyacid with a molecular weight about 10(5) Da and a content of d enantiomer higher than 90% was used in this study. Nearly stoichiometric complexes of poly(gamma,d-glutamate) anions and alkyltrimethylammonium cations bearing linear alkyl chains with even numbers of carbon atoms from 12 up to 22 were "synthesized" by precipitation from equimolar mixtures of aqueous solutions of the two components. All complexes were found to adopt stratified supramolecular structures made of alternating layers of poly(gamma,d-glutamate) and surfactant with a periodicity increasing from 3.2 up to 4.3 nm according to the length of the alkyl side chain. No definite evidence indicative of the conformation adopted by the main chain in these complexes could be afforded. In all cases, the alkyl chains are in an extended conformation and oriented normal or nearly normal to the layer planes. Polymethylene chains with more than 16 carbon atoms were partially crystallized in the complexes in a separated paraffinic phase, whereas no crystallinity was detected for shorter lengths. The crystallized paraffinic phases were found to melt reversibly at temperatures between 40 and 70 degrees C. This process was found to happen with a concomitant expansion-contraction that amounts between 2 and 8% of the long period of the structure but without significant alteration of the layered arrangement.

“…As Cramer estimated [37], the ratio of anti-Markovnikov over Markovnikov addition of M H to double bond might be even 15:1. Other researchers claim that despite steric factors Markovnikov M H addition occurs in majority (65% and more) [38,39].…”

Summary: A series of complexes from poly(aspartic acid) and alkyltrimethylammonium bromide surfactants with linear alkyl groups, containing even number of carbon atoms from 12 up to 22 were synthesized. The complexes were obtained in good yields, are soluble in organic solvents and stable up to temperatures near 170 8C. On the other hand, the paraffinic side chains are able to crystallize depending on the length of the surfactant n-alkyl chain being the main chain of the complexes is arranged in an extended conformation.
