Outermost atoms are atoms of H and understanding of Polymerization, Polyethylene, Polibutadien, Ethylene, Butadiene, Sikloheksen

Vinyl compounds having a double bond can perform additional reactions or continue the process of polymerization, as can be seen in the chemistry textbook in high school. Polibutadien polyethylene and are products of polymerization of ethylene monomer units and butadien single. In 1928, it was found that a mixture of ethylene and butadien will form a unique reaction that results sikloheksen ring. These reactions are very important to get a six member carbon ring, for easy reaction occurs to produce selectively produced without the use of reactants that are not useful. Why not be easily ethylene molecules react with one another to produce siklobutan ring with four members (see reaction scheme II)? The explanation can be obtained from the theory of quantum chemistry.

Furthermore, both types of ring reaction products (A) and (B) in reaction scheme II can be assumed to be produced from ethylene and derivatives butadien which a hydrogen atom is replaced by a formyl group (-CHO) and methoxy group (-CHO3). However, only (A) that can be produced in a real reaction. If some product is produced, we need to make efforts to separate from one another with the consequences of losing a significant amount of reactants. Therefore, a reaction that produces only one product is

very useful in chemical reactions. Quantum chemistry can provide theoretical design for a reaction scheme to produce the selective production of the compounds.

Polymerization is a reaction to the formation of long chains of organic polymers and repetitive. Polymerization classified into several systems: addition-condensation system and the system of gradual chain growth. Other forms of polymerization are similar ring opening polymerization with chain polymerization. Polymerization is the process of merging or small molecules into large molecules

Polyethylene is one of the most widely used polyolefins are commercially due to have many beneficial properties that include resistance to chemicals and conflict of good, easy to set up and printed, lightweight and cheap price.

However, PE has a surface which is hydrophobic due to resistance to chemicals and low surface energy thereby limiting the use of PE. In general, some specific properties such as chemical composition, hidrofilitas, rudeness, kekristalan, electrical conductivity, adhesion force, and kelumasan required for the utilization of these polymers.

1 Unfortunately, for such purposes, natural PE in general do not have the properties that meet the criteria to be used directly in a designation that described above. Therefore, the PE polymers often require modifications to their properties can meet the requirements in accordance with the desired designation.

Various methods have been carried out modifications to improve the surface properties of PE, among others, by using plasma, corona 2, 3 γ4 radiation rays, ultraviolet light, lasers 5, 6 and ion elektron7 beam.8 For this purpose, one of the techniques being developed is the functionalization of the polymer, ie giving a specific functional group which acts as a bearer of new properties on the modified polymer.

Polibutadien is the product of polymerization of ethylene monomer and butadien single unit. In 1928, it was found that a mixture of ethylene and butadien will form a unique reaction that results sikloheksen ring (see reaction scheme I). These reactions are very important to get a six member carbon ring, for easy reaction occurs to produce selectively produced without the use of reactants that are not useful. Why not be easily ethylene molecules react with one another to produce siklobutan ring with four members (see reaction scheme II)? The explanation can be obtained from the theory of quantum chemistry.

Ethylene is a hydrocarbon compound which is not saturated gas state at room temperature. Ethylene can be produced by living plant tissues, at certain times of these compounds can cause significant changes in growth and maturation processing of agricultural products.

Butadiene is one alkadiena, which through polymerization reaction will form polibutadiena (synthetic rubber). Purely Polibuitadiena sticky and weak that is used as an adhesive component and cement. To be more strong and elastic, polibutadiena heated with sulfur vulcanizing process. Polibutadiena chains will be joined by a chain of sulfur. After that, the chemicals such as carbon and pigment added to obtain the desired characteristics.

Sikloheksen is heksena cyclic compounds containing one double bond 2. According to valence bond model, benzene, expressed as a resonance hybrid of two equivalent contributing structures, known as kekule structure. Each kekule structures contribute equally to the hybrid resonance, which means that the CC bonds rather than single bonds and double bonds but also not among them.
