    摘要： Provided is a method of stably producing a water-soluble nonionic cellulose ether powder having a high bulk density at low cost by adding a minimum amount of water. More specifically provided is a method for producing a water-soluble nonionic cellulose ether powder, comprising the steps of: reacting alkali cellulose with an etherifying agent to obtain a reaction product; washing and draining the reaction product to obtain a water-soluble nonionic cellulose ether; mixing the water-soluble nonionic cellulose ether with such an amount of water of 70°C or higher as to make a water content of the water-soluble nonionic cellulose ether become 55 to 90% by weight to obtain a water-containing water-soluble nonionic cellulose ether having a water content of 55 to 90% by weight; cooling the water-containing water-soluble nonionic cellulose ether; and drying and pulverizing the cooled water-containing water-soluble nonionic cellulose ether.

    摘要： The present invention relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2% of HEC by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mV) latex particle size is in the range of about 320-about 850 nm. Paint compositions incorporating the HEC grafted acrylic latex show high viscosity at static conditions and have no color flow and no syneresis compared paints containing a latex without HEC grafting. The present invention also relates to a cross-linking mechanism that cross-links latex particles at ambient conditions. This cross-linking mechanism comprises diacetone acrylamide (DAAM) and methacrylamide (MAM) with or without styrene.
