Novel polyamideimide polymers |
| abstract |
Novel polymers containing amide and imide moieties are produced by reaction of a spirodilactam precursor selected from 4-oxoheptanedioic acid compounds or 1,6-dioxa [4,4] spirodilactones, a primary diamine and an aromatic tricarboxylic acid compound. The polymer products have relatively high glass transition temperatures. |
