Cationic unsaturated saccharides and polymers prepared therefrom, and their use Cationic polymers have a broad spectrum of use. It ranges from cosmetic formulations, in particular for hair care, via ion exchangers to paper auxiliaries and waste water treatment. ...
These techniques however comprise logistical drawbacks due to the different metering of the polymers and to their separate additions. Other polymers may also be introduced into the cellulose suspension in order to improve the properties of the sheet of paper. However, the introduction of polymers of...
Such polymers can be use as polymer matrix or solid support for various chemical substrates such as organic substrates and reagents. Cross-linked poly(vinyl alcohol) polymers and copolymers are also provided. Methods for preparing such polymers as well as several of their uses are also included. ...
A discovery-oriented synthesis and characterization platform uses interchangeable polymer components to explore a large and complex parameter space to find possible combinations of components that satisfy the design rules at multiple nanolithography patterns dimensions. Hongbo Feng , Moshe Dolejsi & Paul F...
Proteinoid synthesis followed our previous publications6,7,8,9; lysine or glutamate (or aspartate) have a major role in this process by initiation the polymerization6,21,22. Thus, all proteinoids used in these studies contain glutamate and/or lysine in their main chains. Briefly, different com...
This allows the expansion of their utility in optical applications requiring high transparency. Controlling transparency allows plastics to serve functions in a wide range of technologies. Let’s get a deeper understanding of: What are transparent polymers and their examples? Which factors affect the ...
