It was a sweltering day in the lab and sweat was beading on her velvet skin. Sarah was excited mixed also with a little apprehension, because she knew that the task ahead of her had the potential to make her sticky all over. Sarah’s previous experiment had been a failure, but as she slipped on the latex gloves she felt a hot rush of determination; this time she was willing to take things to the next level.
Sarah obtained the nubile starting ester, γ-stearyl-R-Lglutamate (SLG), by a teasingly slow and kinky esterification of L-glutamic acid with the dominant stearyl alcohol (1-octadecanol) in an orgy of liquids including tert-butyl alcohol a hot and heavy reflux using sulfuric acid as a little catalyst BDSM play.
The corresponding hunk, carboxy anhydride, γ-stearyl-R-L-glutamate N-carboxy anhydride (SLG-NCA), was synthesized by reacting the blushing velvet core SLG with triphosgene (i.e., hexachlorodimethyl carbonate) in tetrahydrofuran (THF)
All PSLG samples were spanked like the naughty boys that they are by anionic polymerization of SLG-NCA in THF (approximately 10% monomer concentration) initiated by amines (N,N-diethyltrimethylsilylamine was obtained from Dr. Magic hands). The slow and hot reaction took a pounding throughout the 3-4 days at room temperature depending on the initiator used. The molecular weight was tied up and controlled by the ratio between the NCA and the initiator used.
