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.
If all atoms in the monomers are incorporated into the polymer, the polymer is called an addition polymer. If some of the atoms of the monomers are released into small molecules, such as water, the polymer is called a condensation polymer.Most addition polymers are made from monomers containing a double bond between carbon atoms. Such monomers are called olefins, and most commercial addition polymers are polyolefins.he materials commonly called plastics are all synthetic polymers. Polymers are formed by chemical reactions in which a large number of molecules called monomers are joined sequentially, forming a chain. In many polymers, only one monomer is used.
