Abstract: A method is provided for generating aldehyde-functionalized polymers such as GPAM, wherein progress of the aldehyde-functionalized polymer formation is monitored by measuring viscosity using an online viscometer. A method is also provided for enhancing paper strength, said method comprising generating an aldehyde-functionalized polymer, such as GPAM, according to the present disclosure, and combining said aldehyde-functionalized polymer with a fiber slurry or applying it to a paper sheet.
