FIELD: chemistry. ^ SUBSTANCE: there is disclosed inhibition procedure of attack by organic acid, such as acetic acid, of thermoplastic polymer covering the body and/or bottom of a metal container. Said procedure involves heat treatment of all polymer-coated metal parts of the container to be in contact with organic acid with heating the polymer higher than its melting point. ^ EFFECT: polymer coating effectively protects a metal base from attack of organic acids. ^ 4 cl, 4 dwg, 4 tbl, 2 ex |
