Abstract
The invention describes polyamides having both strongly hydrophilic groups and unsaturated groups, the polyamides consequently being water-dispersible and curable.The hydrophilic groups are distributed along the chain, whereas the unsaturated groups are located at the ends.The polyamides of the invention are useful in many applications, especially in the preparation of intimate blends of polyamides with vinyl, acrylic and/or styrene polymers.
