Homogeneous, random interpolymers of ethylene and lesser amounts by weight of olefinically-unsaturated comonomers are prepared in a substantially constant environment, substantially steady-state reaction mixture, in a well-stirred autoclave reactor, in continuous single-phase operation, using elevated synthesis conditions wherein the temperature and pressure are elevated to an amount high enough to approach, reach, or surpass the molecular weight distribution boundary.

Interpolymers of ethylene and unsaturated carboxylic acids

A loop fastener portion including a soft flexible sheet-like fibrous structure having a multiplicity of loops along a first surface adapted to be releasably engaged by a mating fastener portion, and a layer of thermoplastic resin adhered to a second major surface of the fibrous structure which anchors the loops in the fibrous structure and is softenable by the application of heat to adhere the fastener portion to a substrate such as the surface of a disposable diaper.

The disclosure relates to a carpet, a process for manufacturing a carpet and a method for recycling a carpet. The carpet of the present disclosure includes a primary backing having tufts of synthetic carpet fibers protruding from a top surface and, optionally, a secondary backing, with an extruded sheet of an isotactic polyolefin polymer between and integrally fused to a bottom surface of the primary backing and an upper surface of the secondary backing. The process for manufacturing the recyclable carpet includes contacting the extruded sheet with the primary backing and, optionally, the secondary backing, at a temperature sufficiently high to integrally fuse the extruded sheet to the respective backing. The method for recycling synthetic carpet of the type described includes manufacturing the carpet, collecting portions of the carpet, and melting the collected portions to make a feedstock.

Loop materials are provided for touch fastening. The loop materials include a web of nonwoven fibrous material defining a plane, the web including: (a) raised areas (12), elevated above the plane of the web, defining loops constructed for engagement with male touch fastener elements; (b) rib areas (14, 16) surrounding the raised areas to anchor the loops; and (c) between the rib areas, either open areas, or planar areas (18) that are substantially in the plane of the web.

A polymeric blend formed from recycled carpet scrap and selected compatibilizing agents and/or a poly(ethylene-co-omylacetate) and the products produced from such blend.

Recycling of carpet scrap

Improved process for preparing ethylene/vinyl acetate copolymer based hot-melt adhesive backsized tufted carpet wherein polyethylene, polypropylene or ethylene/vinyl acetate copolymer film is used as the secondary backing. Such carpets have unexpectedly and significantly improved tuft pull strength.

Continous process for the production of low gel content ethylene copolymers comprising the in-line addition of molten wax (with or without free radical initiator) into the polymer stream under turbulent conditions after most but not all of the unreacted monomers have been removed. The low gel content ethylene copolymer/wax blends prepared by the above process are particularly useful in coating compositions for paper, paperboard or corrugated board.

Low gel content ethylene polymer/wax blends and process for preparation thereof

Continuous process for the production of reduced melt index, low gel content ethylene copolymers comprising the in-line addition of a solution of a free radical initiator into the polymer stream under turbulent conditions after most but not all of the unreacted monomers have been removed. The reduced melt index, low gel content ethylene copolymers prepared by the above process are particularly useful in coating compositions for paper, paperboard or corrugated board.
