    Abstract: Synthesis methods for creating polymeric compounds comprising dihydroxyphenyl derivatives (DHPD), or DHPp i.e. polymers modified with DHPD, with desired surface active effects are described. The polymer backbone of DHPp has structural or performance features that can be tailored to control physical properties of DHPp, allowing it to be useful for different applications i.e. tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.

    Abstract: The present invention provides an emulsion for pressure-sensitive adhesive, and a pressure-sensitive adhesive product which exhibits high water resistance and high adhesion properties. The emulsion for pressure-sensitive adhesive includes as essential components: a pressure-sensitive adhesive polymer (A) having a glass-transition temperature of -80 to -20 DEG C, a weight-average molecular weight of 150,000 or larger, and a carboxylic acid value of 30 or smaller; a rosin derivative (B) having a weight-average molecular weight of 100,000 or smaller, and containing at least part of the carboxyl groups being alkali salt with a carboxylic acid value of 190 or larger before alkalization; and a compound (C) having a weight-average molecular weight of 100,000 or smaller, and having no carboxyl group but having at least one functional group reactive with a carboxyl group in its molecule. The amount of the rosin derivative (B) is 2 to 30 mass percent when the total amount of the pressure-sensitive adhesive polymer (A) and the rosin derivative (B) in the emulsion is defined as 100 mass percent, and the compound (C) is contained in the emulsion so that the functional group of the compound (C) is in an amount of 0.05 to 10 equivalents with respect to one equivalent of the carboxyl groups of the rosin derivative (B) before alkalization.
