A grass-like artificial surface was installed for the first time in 1964, at Moses Brown School (Providence, Rhode Island) (1). In 1966, artificial turf was installed in the Houston Astrodome in Texas. These surfaces consisted of green pigmented, nylon-6,6 pile ribbon, with a cross-section resembling that of natural grass. Since that period, other fabrics of various pile ribbon and constmctions have continued to become available commercially for indoor and outdoor facihties. 

Other more recent examples of recreational surfaces or components are artificial turf variations for golf tee mats and croquet, permanent resident base layers replacing asphalt or asphalt and shock-absorbing underpad in artificial turf field instadations, and sand-fided turf... 

These grass-like and resident instadations require substantial amounts of synthetic materials. A typical sports field covered with artificial turf requires approximately 15,000 kg of fabric, 15,000—30,000 kg of shock-absorbing underpad, and 5,000—10,000 kg of adhesive and seaming materials. The artificial surface for a 0.40-km miming track may require 50,000—70,000 kg of materials. Paint striping and marking of turf, tracks, and courts cad for additional materials. 

Recreational surfaces must provide certain performance characteristics with acceptable costs, lifetimes, and appearance. Arbitrary but useful distinctions may be made for classification purposes, depending on the principal function a covering intended primarily to provide an attractive surface for private leisure activities, eg, patio surfaces a surface designed for service in a specific sport, eg, track surfaces or a grass-like surface designed for a broad range of heavy-duty recreational activities, including professional athletics, eg, artificial turf for outdoor sports. 

Foi example, nylon pile fabrics, exhibiting higher moisture regain, have different traction characteristics under wet and dry conditions than do polypropylene-based materials. Effects of artificial turf fabric constmction on shoe traction ate given in Table 2. Especially effective in aiding fabric surface uniformity is texturing of the pile ribbon, a process available for the two principal pile materials nylon and polypropylene.

For the purpose of illustrating the recreational surface market, manufacturers and trade names of commercial products are provided in Tables 8 and9. Table 8. Manufacturers and Trade Names of Artificial Turf Surfaces for Multisport Use... 

In terms of surface area covered, artificial turf is the dominant commercial product in the category of artificial surfaces described in this article. Light-duty surfaces are the largest representative, followed by tennis court and multipurpose recreational surfaces. 

Cyclopentadiene oligomers have been formed by vapor deposition of CPD on kaolin to afford a sorbant for removal of oil from water (71). They are also employed as coatings for controlling release rates of fertilizers (72). Thermal addition of sulfur to a mixture of DCPD and CPD oligomers has led to a number of beneficial appHcations such as waste water oil adsorbant powdery foams (73), plasticized backing for carpets and artificial turfs (74), and in modified sulfur cements for encapsulating low-level radioactive wastes (75).

Sports activities would be different today without synthetic polymers. Balls, uniforms, artificial turf, bandages used to wrap sprains, and nets used in hoops and goals are usually made of synthetic polymers.

Recycled rubber is still used as tire derived fuel, but less so than 10 years ago. Another outlet is as an additive to asphalt. Recycled rubber can be used in the plastics industry, for which much development is being done. Large particle size ground rubber or chips are used in civil engineering applications, landscaping, or artificial turf. 

Most plastic products, such as plastic building prodncts, ontdoor furniture, and artificial turf used outdoors, are stabilized against solar UV-indnced damage to ensure full service life outdoors. A discussion of the different stabilization mechanisms and the interesting chemistry associated with stabilization are beyond the scope of this chapter. The reader is directed to other works that discuss the topic comprehensively (Wypych, 2010). 

Artificial turf n. A manufactured carpet having the appearance of grass. It is used to replace grass in sports arenas, yards, etc. Also see recreational surfaces. 

Recreational surfaces n. Manufactured surfaces providing consistent properties, durability, and special characteristics as needed for the specific application. Included are artificial turf, pool decks, indoor-outdoor carpeting, tennis court surfaces, etc. Most types of constructions (knit, woven, tufted, and non-woven), and most polymer types find use in this market. The polyolefins are particularly prominent in these applications.
