copolymerization การใช้

• Maleic anhydride is the precursor to various resins by copolymerization with styrene.
• To get more control on the regiospecific polymer synthesis, copolymerization was proposed.
• Degradable polyester can be synthesized via radical ring-opening homo-and copolymerization.
• The development of coordination polymerization that enables copolymerization with polar monomers is more recent.
• This causes equal rates of consumption for copolymer formation and leads to random copolymerization.
• Despite intensive efforts, few catalysts have been successfully commercialized for the copolymerization of polar monomers.
• One major effort was on DuPont Versipol post-metallocene catalysts for ethylene coordination polymerization and copolymerization.
• Hemichromes form an insoluble macromolecule ( macromolecular aggregate ) by copolymerization with the cytoplasm of band 3.
• With Horne's inquisitive nature and determination, he tried the copolymerization of ethylene and isoprene.
• Developments from this have included the introduction of coordination copolymerization for producing high surface area materials from simple feedstocks.
• In most cases titanium dioxide is used with copolymerization and volatile matter in producing such synthetic rubber for textile use.
• Merrifield Resin can be prepared by chloromethylation of polystyrene or by the copolymerization of styrene and 4-vinylbenzyl chloride.
• One example is the alternating tendency of the copolymerization of maleic anhydride ( electrophilic ) and styrene ( slightly nucleophilic ).
• The most prevalent synthetic rubbers are styrene-butadiene rubbers ( SBR ) derived from the copolymerization of styrene and double bonds.
• The ratio of monomer to macromonomer molar concentrations as well as their copolymerization behavior determines the number of chains that are grafted.
• Cluster compounds often consist of at least one functional group that allows an interaction with an organic matrix, for example by copolymerization.
• A recent hot topic among scientists has been the study of radical ROP to undergo copolymerization for the production of copolymers with ketoester linkages in the main chain.
• Modification of the polymer through copolymerization or through the addition of non-reactive side chains to monomers before polymerization can also lower " T " g.
• Adding additives or copolymerization of PNIPA can lower the lower critical solution temperature to temperatures around human body temperatures, which makes it an excellent candidate for drug delivery applications.
• It is applicable in the areas of free radical and controlled radical homo-and copolymerization, polyelectrolyte synthesis, heterogeneous phase reactions, including emulsion polymerization, adaptation to batch and continuous reactors, and modifications of polymers.
