Abstract: Two stage film-forming polymers having a soft first and a hard second stage are prepared by emulsion polymerizing the first stage and then, in the presence of a coalescent, the second stage. The polymers combine low MFT with superior early block resistance and high temperature hardness.

Abstract: It has been discovered that the adhesion of latex coatings to concrete surfaces can be significantly improved by prior treatment of the surface with an air curable, water soluble polymer. Preferred water soluble polymers cure oxidatively in a manner similar to drying oils.

Abstract: Process for the production of a crimped metal-coated continuous-filament or a crimped yarn of a plurality of metal-coated filaments which filament or yarn is adapted for combination with other filaments to form an improved yarn for use in making anti-static fabrics, such as pile carpets or the like, wherein the continuous-filament or yarn comprising a plurality of filaments is first made into a knitted fabric, the fabric is treated to deposit a continuous metal coating on the filament or yarn thereof, and the coated fabric thus obtained is deknitted, thereby yielding the metal-coated continuous-filament or yarn in a crimped disposition characteristic of the knitted loop construction existing in the knit fabric. Heat treatment of the crimped filament or yarn after the metal-coating step significantly improves its anti-static properties when incorporated into fabric.
