and towel in most cases however especially in printing papers no wet strength agent is required and the dendrimeric polymer is added to the papermaking stock without the addition of a wet strength agent in particular the papermaking stock may be free of wet strength agents the dendrimeric polymer enhances retention of papermaking components in a cellulosic sheet formed from a cellulosic dispersion of papermaking components and produces a cellulosic sheet having an enhanced content of the papermaking components as compared with a cellulosic sheet formed from a second cellulosic dispersion which differs only in that it is free of the dendrimeric polymer on the other hand an aqueous fraction of the papermaking stock of the invention separated from the cellulosic sheet formed from the stock has a diminished content of papermaking components as compared with an aqueous fraction separated from the aforementioned second cellulosic dispersion free of the dendrimeric polymer the term dendrimeric macromolecules is understood as embracing very generally highly branched macromolecules that emanate from a central core and are synthesized through a stepwise repetitive reaction sequence dendrimeric macromolecules are often referred to as u201c starburst u201d polymers dendrimers are a new class of macromolecules with a hyperbranched structure this structure is well defined in terms of chemical composition and three dimensional configuration dendrimers are synthesized in a stepwise manner which provides unique control over chemical and physical properties this control allows for the development of products which are tailored to specific applications for example the end groups of the dendrimers are very well accessible for all kinds of modification reactions examples.
