Anders’ polymer

The broadest range of 2.5-10.5 pH has been observed for microspheres of Anders polymer made of copoly (asp, ser, glu, gly, ala, om, lys, his, arg). Heating of mixed amino acids with sea water salts yields acidic and basic proteinoids, simultaneously, which are stable, as microspheres, in alkaline solution. ...

These relations are illustrated in the phase diagram in Fig. 10. C3 chondrites, having formed above the 400 K threshold for formation of hydrogenation catalysts (Anders et al., 1976), contain carbynes but little or no polymer or organic compounds.

Obviously, the residence time and its distribution only partially determine the chance of degradation in an extruder. The other factors that play an important role are the actual stock temperatures and the strain rates to which the polymer is exposed. The actual stock temperatures and strain rates are closely related. In the extruder, there are two major areas of concern the screw channel and the flight clearance. Janssen, Noomen, and Smith [65] studied temperature distribution of the polymer melt in the screw channel. Temperature distribution of the polymer right after the end of the screw was measured, for instance, by Anders, Brunner, and Pan-haus [66]. The temperature variations in the screw channel at the end of the screw were reported to be less than 5 to 10°C and relatively close to the barrel temperature. More recently, Noriega et al. [145] measured melt temperature distribution with a thermocomb and found temperature variations as high as 20 to 30°C.
