从1970到1980，美国对塑料的需求从200亿磅增加到了500亿磅。塑料的成功主要是由于其广泛的应用，由于其广泛的性能，塑料可以替代金属、玻璃、陶瓷、纸张、天然纤维、包装材料、消费产品、管道、家具，等等…… 塑料最重要的性能在于其重量轻，耐破损，能巩固功能部件，想对便宜，易于自动化生产，生产成本较低……
From 1970 to 1980, the demand for plastics in the United States increased from 20 to 50 billion pounds. The success of plastics is due to the broad spectrum of applications, attributable to a wide range of properties which made plastic replace metals, glass, ceramics, paper, natural fibers, packaging, consumer products, piping, furniture, etc...
The important properties of plastics are light weight, breakage resistance, ability to consolidate functional parts, relatively inexpensive, easy automated production, lower costs of manufacturing,..
With the accomplishment of substituting all possible traditional materials, slower economic and population growth in the developed regions of the word and polymer down grading (due to environmental protection, reinstitution of older values) becoming a significant trend, the polymer growth rates slowed down. Intercompetition among polymers in addition has increased and the development risk of new polymers often outweighs the potential commercial reward.
These factors favored the relative inexpensive route of combining two or more commercial available polymers through alloying or blending in order to create product differentiation for new applications.
