In addition several other materials have been reported by industrial companies, but have not at the time of writing been commercialised. These include the product of condensation of 2,2-bis-(p-aminocyclohexyl)propane (VI) (Figure 18.28) with a mixture of adipic and azelaic acid (Phillips Petroleum), a research material produced in the old German Democratic Republic obtained by melt condensation of /ranj -cyclohexane-l,4-dicarboxylic acid (VII) (Figure 18.28) and the two trimethylhexamethylenediamine isomers used in the manufacture of Trogamid T, and another amorphous material (Rilsan N by Ato Chimie). 

Circulation Test Conditions for Additive Solutions in Porous Media The sand/kaolinite mixture described above was used to form sandpacks in a Rilsan cell (13 or 30 cm long, 2.5 cm in diameter, 36 % porosity). The corresponding solid/liquid ratio was then 4.72 g/cc. 

Nylon-11. Nylon-11 [25035-04-5], made by the polycondensation of 11-aminoundecanoic acid [2432-99-7], was first prepared by Carothers in 1935 but was first produced commercially in 1955 in France under the trade name Rilsan (167) Rilsanis a registered trademark of Elf Atochem Company. The polymer is prepared in a continuous process using phosphoric or hypophosphoric acid as a catalyst under inert atmosphere at ambient pressure. The total extractable content is low (0.5%) compared to nylon-6 (168). The polymer is hydrophobic, with alow melt point (Tm = 190° C), and has excellent electrical insulating properties. The effect of formic acid on the swelling behavior of nylon-11 has been studied (169), and such a treatment is claimed to produce a hard elastic fiber (170).

In the different polyamides the absorbed water has the following apparent density nylon 6 = 0.86, Rilsan = 0.72, Trogamid = 0.67. Immersion in water up to 80 °C. has little influence on the properties. In boiling water, however, turbidity is observed, and this is especially evident in a thin film. An alkaline pH adjustment of the hot water reduces this phenomenon. The turbidity is not accompanied by degradation. Dried turbid material can be processed to clear specimen. Electronic...

Grade Nylon 66 is a condensation product of adipic acid and hexamethylenediamine developed by Car-others in 1935. Adipic acid is obtained by catalytic oxidation of cyclohexane. Nylon 6 is a polymer of caprolactam, originated by I. G. Farbenindustrie in 1940. Nylon 4 is based on butyrolactam (2-pyrroli-done) its tenacity, abrasion resistance, and melting point are said to be about the same as for the 6 and 66 grades. It has excellent dyeability. Nylon 610 (TM Tynex ) is obtained by condensation of sebacic acid and hexamethylenediamine, and nylon 11 (TM Rilsan ) from castor bean oil (developed in France). Nylon 12 (also called Rilsan 12) is made...
