Yesterday's entry on epoxides may have brought to mind epoxies. The similarity isn't a coincidence. Chloromethylepoxide, or "epichlorohydrin," is the basis for many epoxy adhexives.
One tube contains some epoxide, such as epichlorohydrin, along with some bisphenol A - the very same stuff you find in polycarbonate. This is actually partially polymerized ("oligomers") - the degree of polymerization and ratio of epichlorohydrin to bisphenol A can determine how hard an epoxy you get - this is often the basis for "soft" epoxies.
It's not over yet, though. Tomorrow I'll cover what's in that other tube.

Yesterday's entry on epichlorohydrin got us halfway to an epoxy resin, with the aid of good old bisphenol A. In that other tube, you'll often find some sort of amine, which, when mixed with a prepolymer like that formed with epichlorohydrin-bisphenol A, heats up and hardens.
This triamino-phenol…
OK this post was a warm up for today.
Microtubules are long hollow polymers. They are also polar. Their minus ends are inert and are found towards the cell center while their plus ends grow and shrink and are found towards the cell periphery.
Question: Why are microtubules hollow?
Well you might…
I've seen a few links passed around to this Tom Siegfried post about science literacy, which is mostly a familiar story about how polls show most Americans giving incorrect answers to science questions. The sort of stuff you find in the NSF's Science and Engineering Indicators report. What's…
Maybe I'm not the right person to bring this message as I drink very little in the way of fluids each day, at least compared to my students who will, I am sure, have to be surgically removed from their water bottles. Of course I've also had kidney stones twice, so I'm not suggesting anyone do as I…

Epichlorhydrin was also a very minor contaminant in commercial trichloroethylene (TCE), a common degreasing agent that is a prevalent groundwater contaminant. When NIH did animal bioassays of TCE in the seventies they found it was an animal carcinogen but had to redo the results because of the epichlorhydrin contamination (also a carcinogen).
Epoxy resins usually initiate failure at the opened epoxide linkage, hence high temp systems with anhydride rather than amine cures, e.g., diglycidylbisphenol-A plus styrene maleic anhydride copolymer or bridged bis(phthalic anhydride)s. Improved properties are also obtained by being more clever than bisphenol-A.
The condensation of phenol plus aldehyde or ketone in dilute aqueous sulfuric acid is general and rapid. It is one of the few facile routes to quaternary carbon centers. Acetone is cheap. Other ketones give much more interesting bisphenols - hexafluoroacetone, cyclopentanone, acetophenone, benzophenone, fluorenone, [dihydro]isophorone... and [N-methyl] 2,2,6,6-tetramethyl-4-piperidone (triacetoneamine) or N-hydroxy-2,2,6,6-tetramethyl-4-piperidone by using hydroxylamine rather than ammonia.
High MW polycarbonate plastics with more hindered quaternary carbons polymerized in situ by opening of low viscosity molten cyclic oligomers have extraordinary high temperature properties.
