Abstract: Terpolymers which have Fikentscher K-values of from 8 to 100 and comprise 50 mole percent of maleic anhydride units, from 35 to 45 mole percent of 2,4,4'-trimethylpent-1-ene units and from 5 to 15 mole percent of 2,4,4'-trimethylpent-2-ene units, and processes for their preparation by polymerizing 50 parts by weight of maleic anhydride, from 35 to 180 parts by weight of 2,4,4'-trimethylpent-1-ene and from 0.6 to 6 parts by weight of 2,4,4'-trimethylpent-2-ene per part by weight of 2,4,4'-trimethylpent-1-ene employed, in the presence of a free-radical initiator at from 60 DEG to 200 DEG C. and a pressure of from 1 to 20 bar, and separating the terpolymers from the unconverted monomers.

IPC: C08G69/26 , C08G69/28

Abstract: A glass-clear nylon based on aromatic dicarboxylic acids and dialicyclic diamines is prepared by polycondensing isophthalic acid with a mixture of 3,3'-dimethyl-4,4'-diamino-dicyclohexylmethane and hexamethylenediamine. The nylons may be used for the production of moldings, especially by injection-molding.
