Abstract: A hot melt adhesive is provided that is useful in the production of textiles, such as a tuft carpet, contains a blend of constituents that allows synthetic carpet members to be fully recycled without first separating the adhesive from the carpet members. The adhesive includes (a) from about 5 to about 30 weight % of a copolymer of an alkyl acrylate having from 2 to 18 carbon atoms; (b) from about 5 to about 50 weight % of a wax and desirably a C10 wax; (c) up to about 75 weight % of a filler; and (d) from about 0.1 to about 10 weight % of an aliphatic carboxylic acid having from 8 to 24 carbon atoms.

Abstract: Disclosed is a method for controlling or reducing the amount of powder fines present in a polyethylene fluidized bed reactor. The method uses hydrocarbons that are inert with respect to the polymerization reaction, as well as using reactive olefins. The reduction of powder fines provides significant operating benefits in the fluid bed process, including reduced formation of powder agglomerates in the reactor and reduced fouling of equipment in the recycle gas stream.
