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 a polyolefin polymer composition between and integrally fused to a bottom surface of the primary backing and an upper surface of the secondary backing. The extruded sheet polymer composition comprises at least 10%, preferably, at least 20% by weight of a syndiotactic polypropylene product. The extruded sheet polymer composition may further comprise less than 40% by weight of an impact modifier. 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 extruded sheet provides excelled adhesion and abrasion properties.

Settlement of barnacles on surfaces in a marine environment is inhibited by employing as a construction material for said surface of polymers including methyl methacrylate and an effective amount (preferably about 2% to about 10%) of a copolymerizable N-substituted maleimide.
