    Abstract: The present invention provides for a polymer composition comprising a carboxylic acid-containing polymer (CP) and an amino-containing polymer (AP). The CP and the AP are capable of crosslinking to each other through ionic interaction of the carboxylic acid and amino functional groups. The CP and the AP can be unlinked by increasing the pH of the polymer composition to about pH 13.
