1.Premium gas is pricier than regular gas. 2.Premium gas has higher octane ratings than regular gas. 3.Premium gas is ideal for the high-performance class and high-compression cars while regular gas is already good for most of the other regular to mid-class cars.4.Premium gas is believed by some to have more detergents (that serve to clean the engine) than regular gas.astly, some believe that premium gas has more detergent properties than regular gas. This means fewer residues left for premium gas users. However, it has also been discovered that most governments already regulate the required detergents in gasoline.
Lignin, a natural polymer found in wood, is a polyaromatic polyol that is readily available and relatively inexpensive. Lignin structure is dependent on wood species and processing conditions [2] . Commercially, lignin is obtained as a by-product of âwood freeâ papermaking.
Best Answer: Naturally occurring polymers include rubber and amber. A polymer molecule has a high molecular mass and is comprised of many smaller, repeating subunits or monomers.Polymers may be found in nature, such as the DNA and proteins found in living cells, or created in laboratories or factories.Polymer molecules come in many shapes and sizes. polymer molecule has a high molecular mass and is comprised of many smaller, repeating subunits or monomers.
