Electrodeposition of Water-Dispersible Polymersmental requirements. (See also the chapter by T. J. Miranda.) Much work has been done, aiming at reduced use — or elimination — of organic solvents as carriers of coating materials. One of the outstanding innovations in the exclusive use of water as carrier of coating materials is the electrocoating

Water-Based Finishes in Response to Environmental Constraintsgs requirements for appliances range from the severe environments of the washer and diswasher to less severe conditions of the dryer and the refrigerator. As a result, the coating industry has developed finishes like the epoxies for primers and the thermosetting acrylics for topcoats (1). These coat

Some Properties of Carbamoylated Polyethylenimine and Its Hydrolysis Productudy, it was found that polymers having primary and secondary amino groups, such as polyethylenimine hydrochloride (PEI.HC1) and poly(.-lysine) hydrobromide, easily react with cyanate ions to form carbamoylated polymers. In the present chapter, we report the details of the preparation of carbamoylate

Extracellular Microbial Polysaccharides: New Hydrocolloids Having Both Fundamental and Practical Impucture and properties. Only within approximately the last thirty years,however, has the practical potential of these macromolecular biopolymers been given serious consideration. Thus far, only a beginning has been made in discovering microbial sources, selecting products suitably constituted for spe

Preparation of Cationic Polyelectrolytes by Spontaneous Polymerizationand it can be noted that the syntheses of these water-soluble polyions has been concerned primarily with the preparation of ionene polymers (2) by polycondensation reactions, with the polymerization of cationic vinyl monomers in which the positively charged site is located far from and not in resona
