Level 2 Papermaking - Wet Strength Aids

[@danielmartin7708]

Hi Steve, I greatly appreciate your videos. They are very instructive. I do have a question on the slide which shows the structure of dialdehyde starch. In parenthesis below the label of Dialdehyde starch it has the chemical name of polyacrylamide. Is this an error or just a reference for another chemical for temporary wet strength?

Well spotted Daniel, 'polyacrylamide' should not be there. My apologies. I copied that slide from another presentation to give myself a start, and forgot to remove the word.. Thanks for pointing it out
