Provided is a process for preparing an alcoholic solution of a polyvinylpyridine polymer having biocidal and biocompatibility properties. The alcoholic solution is ready-to-graft in order to confer biocidal properties to various surfaces and to prevent biofilm formation on such surfaces. Also provided are methods of using the alcoholic solution, such as for controlling the growth of bacteria, fungi and/or viruses, and/or for preventing digestion of wood cellulose by wood-boring insects.

The present disclosure relates to an oxidation-reduction polymer including a transition metal complex, which has a unique structure, and so can be prepared in a simpler step compared to a conventional method, and can increase the immobilization rate of the transition metal complex and facilitates the introduction of a functional group or a linker, a method for preparing the same and an electrochemical biosensor comprising the oxidation-reduction polymer.

The present disclosure relates to polymers which contain a hydrophobic and hydrophilic segment which is sensitive to pH. In some aspects, the polymers form a micelle which is sensitive to pH and results in a change in fluorescence based upon the particular pH. In some aspects, the disclosure also provides methods of using the polymers for the imaging of cellular or extracellular environment or delivering a drug.

A polymer complex is disclosed which is the reaction product of one or more polymers having a terminal or pendant hydroxyl group, or a terminal or pendent carboxyl group, or combinations thereof, with at least one metal complex and one alkyl phosphate. This polymer complex acts as an adhesion promotion agent as well as a viscosity stabilizer when formulated in a printing ink or coating.

A crosslinked polyolefin separator which has gels with a longer side length of 50 μm or more in a number ranging from 0 to 3 per 1 m.sup.2 of the separator, and shows a standard deviation of absorbance ratio between the center of the separator and the side thereof ranging from 0.01 to 0.5 is provided. A method for manufacturing the crosslinked polyolefin separator is also provided. The method includes (S1) preparing a polyolefin porous membrane, and (S2) applying a coating solution containing an initiator and alkoxy group-containing vinylsilane onto at least one surface of the porous membrane. The coating solution can permeate even to the inside of exposed pores. Thus, it is possible to provide a crosslinked polyolefin separator in which silane crosslinking occurs uniformly even inside of the pores.
