Answer. A polymer is defined as a large molecule which is formed by repetition of similar or different kinds of monomers (where the monomer is a small molecule which repeats itself to form a polymer). Artificial polymer. When it comes to polymers, green and natural are not the same.As their name implies, natural polymers (or biopolymers) are polymers that occur naturally or are produced by living organisms (such as cellulose, silk, chitin, protein, DNA).By a wider definition, natural polymers can be man-made out of raw materials that are found in nature. Some synthetic polymers are biodegradable and can be tailor-made easily. Polyethylene (most commonly known as polyethylene): It is derived from unsaturated hydrocarbons. Carbohydrates: Carbohydrates, or sugars, contain carbon, hydrogen, and oxygen atoms. The monomer is a liquid petrochemical. Moving on to classifying the types of polymers, we can broadly classify the polymers as: 2. This form of starch is often called thinned starch. Even though starch and cellulose are both made from the same sugar (glucose) , they act very differently (because the glucose molecules are joined together differently). The monomer of starch is – D – glucose. Yes starch is a polymer made up of many glucose molecules. Cellulose, another natural polymer, is the main structural component of plants. The molecules of starch consists of 2 kinds of glucose polymers namely amylopectin and amylose which are the main component of starch in most of the plants. It has a low cost and can be easily extracted from a large variety of plants. Starch is a natural polymer which possesses many unique properties and some shortcoming simultaneously. W-Natural ® TP range is a thermoplastic starch polymer made of certified non-GMO corn and W-Natural ® CP range is the customized bio-polymer according to the application areas. What does contingent mean in real estate? They are often derived from various biomass sources, the most widely used being starch, which is a natural polymer that can be incorporated in various materials. We have two types of synthetic plastic; that is low-density plastic which is chemically inert, robust and destitute in conducting electricity. Proteins: They are the building blocks for animals. The molecules of starch consist of 2 kinds of glucose polymers namely amylopectin and amylose which are the main component of starch in most of the plants.
