Abstract
Synthetic polymers having moieties capable of covalent or hydrogen bonding to cellulose and one or more amphiphilic moieties are disclosed. These polymers are capable of providing two distinct properties to paper products, such as tissues, which properties heretofore have been imparted through the use of at least two different molecules. The backbone of these synthetic polymers is based on modified vinyl polymers, such as polyvinyl alcohol, polyacrylamides and polyacrylic acids.
