WebAnswer (1 of 3): ethylene is unsaturated while ethane is saturated. Alkane is paraffins (less reactive). addition reaction is simple as compare to the substitution reaction. Therefore … WebThe major difference between plasma polymerization and plasma grafting is that plasma polymerization coats the substrate rather than covalently binding species to the modified polymer surface (Barry et al., 2005).Therefore, if one is using the same monomer, the plasma-polymerized polymers will show different chemical and physical properties as …
WebPolyacetylene (PA) is an organic polymer discovered by Hideki Shirakawa, Alan Heeger, and Alan MacDiarmid with the chemical formula of (C 2 H 2) n.It forms by the oxidative polymerization of acetylene monomer to form a continuous linear chain of olefin groups. The conductivity of PA in the doping stage is highest among the conductive polymers.
WebRecent work has shown that acetylene itself may be polymerized using metathesis catalysts, even though the yields of polymer are extremely low. 26 Catalysts derived from WCl 6 and alkylaluminums, alkyl halides and butyllithium have been used. The activities of these catalysts for the polymerization of acetylene are likely to be low because the ... black circle in excelWebPolymers are very useful for day-to-day lives as they possess properties such as elasticity, toughness and can form semi-crystalline and amorphous structures.
