| abstract | The invention comprises polymers containing the recurring structural unit: <FORM:0958863/C3/1> where R is a dimeric radical derived from a fat acid having an aliphatic hydrocarbon chain of 8 to 24 carbon atoms. The polymers are obtained by dimerizing a fat acid, converting the dimer to the corresponding dinitrile or diprimary diamine, and then hydrogenating the dinitrile or diamine e.g. at a pressure of 25 to 100 p.s.i.g. and a temperature of 200 DEG to 290 DEG C. in the presence of a catalyst. Copolymers may be obtained by hydrogenating a mixture of dinitriles or a mixture of diprimary diamines. In examples polymers are obtained from a dimer dinitrile prepared from dimerized linoleic acid, and from a dimer diamine prepared by hydrogenating the dimer dinitrile; two of the examples describe copolymers prepared from adiponitrile and from metaxylylene diamine. |
