的关键difference between oligomer and polymer is that the oligomer forms when few monomers undergo polymerization whereas the polymer forms when a large number of monomers undergo polymerization. Polymers are large macromolecules that contain a large number of repeating units; we call them monomers. The monomers undergo a process called polymerization in order to […]

的关键difference between expanded and extruded polystyrene is that we produce expanded polystyrene (or EPS) from solid beads of polystyrene while we produce extruded polystyrene (or XPS) from solid polystyrene crystals. Expanded polystyrene is a type of foam made from polystyrene. It is a lightweight, rigid and closed cell insulation. Extruded polystyrene is another […]

的关键difference between polystyrene and Styrofoam is that the polystyrene is a form of synthetic aromatic hydrocarbon polymer whereas the styrofoam is a commercial brand of polystyrene. Polystyrene is a polymer material. It forms from the polymerization of styrene monomer. Thus, it is available as both solid or foam, and it is common because […]

的关键difference between saturated and unsaturated polyester resin is that the saturated polyester resins have no double bonds in their main chain whereas the unsaturated polyester resins have double bonds in their main chain. A polyester is a polymer compound that forms from the condensation reaction between a polyol and an acid. Therefore, we […]

的关键difference between suspension and emulsion polymerization is that mechanical agitation is used in suspension polymerization while emulsion polymerization usually occurs in an emulsion. Polymerization is the formation of a macromolecule via the combination of a small molecule named monomers. This macromolecule is a polymer. Therefore, monomers act as the building blocks of polymers. […]

的关键difference between Lucite and Acrylic is that the Lucite is the tradename for polymethyl methacrylate whereas Acrylic is the general chemical name of polymethyl methacrylate. Acrylate polymers are what we call plastics. They have noted transparency, resistance to breakage, elasticity, etc. Therefore, in general, we call them acrylic polymers. The most common type […]

的关键difference between organic and inorganic polymers is that the organic polymers essentially contain carbon atoms in the backbone whereas the inorganic polymers do not contain carbon atoms in the backbone. Furthemore, most of the organic polymers are simple structures. But, almost all of the inorganic polymers are highly branched complex structures. Backbone of […]

的关键difference between Kevlar and carbon fibre is that the Kevlar essentially contains nitrogen atoms in its chemical structure whereas the carbon fibre does not contain nitrogen atoms and mainly contains carbon atoms in its chemical structure. Kevlar and carbon fibre are two forms of synthetic fibres. Both these materials have a high strength. […]

的关键difference between PP and PPCP is that the PP (or polypropylene) can be either a homopolymer or a copolymer whereas the PPCP (or polypropylene copolymer) is essentially a copolymer of the polypropylene. The term PP stands for polypropylene. We can find it in two basic forms; the homopolymer and the copolymer, due to […]

交叉与聚合物之间的关键区别d linear polymer is that the monomer units of linear polymers have end-to-end links, resembling the beads in a necklace, whereas cross linked polymers are made up of chains that are joined together by a series of covalent bonds, called cross-links. Polymers are the compounds consisting of small […]
