They are formed from repeated combinations of simplest units known as monomers and the process of formation of polymers is called polymerization. Complete step by step answer: (a)Addition Polymer-
SpletAn addition polymer is a polymer that can form from monomers without the formation of by-products. Also, there are polymers that form when bits of the monomers break off and the remainders bond together. These are called condensation polymers. Definition: Condensation Polymer SpletThe molecular mass of polymers is up to 103–107u. In a polymer, strong covalent bonds connect different monomer units. Natural and synthetic polymers can be used to produce these materials— for instance, polymers like polythene, rubber, and nylon 6, 6.
SpletAddition polymers include polystyrene, polyethylene, polyacrylates, and methacrylates. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, …
SpletThe question asks how the mass of an addition polymer compares with the mass of the monomers that it was made from. As no by-products are formed when an addition polymer is created, the mass of the addition polymer must … gucci black tights dupeSpletIn step growth polymerization, all molecules that is, polymer, oligomer and monomer can react with any other molecule. In chain addition polymerization, only monomers react to the active sites at the end of the growing chain. Molecular Weight.
