Low Glass Transition Temperature Aromatic Polyamides.
Abstract
This invention relates to aromatic polyamides. In particular, it relates to amorphous aromatic polyamides having low glass transition temperatures. Considerable effort has been expended on research leading to the preparation of molecular composites. From this research has risen the need for new thermoplastic polymers to act as matrices for rod-like polymers in the molecular composites. Rod-like polymers are generally processed from a strongly acidic medium, such as methanesulfonic acid. It is therefore necessary that the thermoplastic matrix be soluble and chemically stable in such strongly acidic medium. Patent applications. (jes)
