MATSE 441 Exam 1 Questions And Answers
Polymer Production ANS✔✔ The production of polymers increases every year and will continue to do so, 7 million tons
in the world in 1960 to 196 million tons in 2005 and to continue reaching over 365 million tons in 2015, 540 million tons
in 2020, using a more conservative annual rate of 6.5 %. Total world production/consumption of plastics, since the
beginning, at the turn of the twentieth century, kept an average annual rate of growth of 15 %, or doubling every five
years, until 1975-1979, when this trend was broken at the first oil shock. This high growth rate was never achieved
again, the average annual growth rate of plastics was 15% from 1960 to 1974, and 8% thereafter, from 1974 to 2000,
and 2005.
