摘要： The present invention provides a process for preparing stable, uniform dispersions of chain extenders in polyurethane-forming polyol. The preferred chain extender is hydroquinone di(.beta.-hydroxyethyl)ether. The process comprises an adiabatic quenching step in combination with an annealing step. The inventive process avoids the need for slow, carefully controlled cooling schemes.

摘要： Disclosed are articles, such as smoke filters, which contain fibers that have complex geometry in combination with tobacco smoke modifying agents such as flavorants. The fibers are preferably made of a polyester such as poly(ethylene terephthalate) and preferably are capable of spontaneously transporting water or n-decane on their surfaces. The articles of the invention result in improved delivery of the tobacco smoke modifying agent to the user.

摘要： Disclosed is a process for the formation of olefin-vinyl alcohol copolymer pellets which comprises mixing particles of the copolymer with water to obtain a wet cake containing about 20-70% solids by weight to thereby obtain a plasticized mass of the copolymer, thereafter extruding the copolymer at a temperature of about 5.degree.-7.degree. C. below the melting point of the mass through a nozzle to form a rod, and dividing the rod into individual pellets.
