Chloroprene production can be equated approximately to the amount of polymer produced. World production of dry polychloroprene was 135 thousand tonnes in 1960, 254 thousand tonnes in 1970, 314 thousand tonnes in 1980 and 321 thousand tonnes in 1989 (Stewart, 1993). World polychloroprene capacity in 1983 was reported to be (thousand tonnes) United States, 213 Germany, 60 France, 40 United Kingdom, 30 Japan, 85 and centrally plarmed economy countries, 220 (Kleinschmidt, 1986). Current capacities are reported to be (thousand tonnes) United States, 163 Germany, 60 France, 40 United Kingdom, 33 Japan, 88 central Europe and the Commonwealth of Independent States, 40 and People s Republic of China, 20 (International Institute of Synthetic Rubber Producers, 1997).

A final quantitative example is that of determining the % ethylene in ethylene-propylene copolymers (EPM). The International Institute of Synthetic Rubber Producers (IIRP) Technical/Operating Committee and the American Society for Testing and Materials (ASTM) cooperated to produce an updated standard method [56]. They also produced a set of standards with the ethylene content established by 13C NMR. Those standards were utilised by Parker and Waddell to study the photoacoustic determination of % ethylene [57]. Three of the four infrared band ratios specified by ASTM were measured, 1378/1462, 1378/722, and 1156/722. The fourth one, 1156/4255, was not used since it involves measurements in the near-IR region. Baselines were drawn by the valley-to-valley technique as illustrated in Figure 2.11. 

The International Institute of Synthetic Rubber Producers (IISRP, Houston, Texas, USA) is an international non-profit association of synthetic rubber producers with 41 corporate members domiciled in 20 countries. IISRP represents 95% of the world supplies of synthetic rubber.
