Development Trends
With the increase in the level of performance required for polypropylene quality in recent years, a variety of ideas and contrivances have been integrated into the production process for polypropylene.
There are roughly two directions for the specific methods. One is improvement of uniformity of the polymer particles produced using a circulation type reactor, and the other is improvement in the uniformity among polymer particles produced by using a reactor with a narrow retention time distribution.

Famous quotes containing the words development and/or trends:
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”

“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
