MODIFICATION OF COPOLYAMIDES VIA POLYMERA NALOGOUS REACTION WITH GLYCIDYL ETHERS

The reaction of copolyamides with phenyl glycidyl ether (PGE) and glyc idyl oxypropyl-3-triethoxy silane (GPTS) in the presence of anionic ca talysts leads to the formation of grafted polyamides. Octanoic acid oc tylamide (OOA) and a copolyamide of polyamides 6, 66 and 11 were used as polyamide model compounds. The anionic centres were introduced by r eaction of the amides with sodium methoxide in boiling toluene. About 15% of the amide groups react with PGE and OPTS. In the presence of OP TS, polycondensation reactions occur and crosslinked products are form ed.
