Natural polymers are starch, cellulose, natural rubber and proteins. Three synthetic material is a synthetic polymer. Polymers are increasingly being replaced by metal, as an important material used in modern society.

There is a natural polymer starch, cellulose, natural rubber and protein, and so on. 3 The synthetic material is a synthetic polymer. Polymer is being increasingly replaced metal used in modern society, has become an important material.

The natural high polymer has the starch, the cellulose, the natural rubber and the protein and so on.Three big composition material are the synthesized high polymer.The high polymer more and more many is substituting for the metal, becomes important material which the modern society uses.

Natural polymers and proteins such as starch, cellulose, natural rubber. Three synthetic materials are synthetic polymers. Polymers is increasingly replacing metal, became modern societies use the important material.
