1416066 Nylon and polytetramethylene terephtalate nets CONWED CORP 16 July 1973 [27 Sept 1972] 33702/73 Heading B5B [Also in Division C3] Nylon or polytetramethylene terephthalate are extruded into net-like products (reticulated films) wherein the polymer melt has induced in it 1 to 10% by wt of a polyolefin lubricant comprising a homopolymer of an olefin or a copolymer of two or more olefins having a ASTM Test melt index of not greater than 100. Examples illustrate the use of nylon 6, polytetramethylene terephthalate and nylon 66 as the extruded polymer and polypropylene, polyethylene, an ethylene-propylene copolymer, an ethylene-hexene copolymer as the lubricant. Also specified are high mol. wt. polypropylene, polybutylene and polypentene.
