Organic polymer Knowledge Fair


Exercise must master polymers, monomers, chain, degree of polymerization, addition polymerization reactions,Oakley sunglasses sale, condensation reactions, concepts, and to grasp the characteristics of monomers and reaction type. First, the structural characteristics of an organic polymer. Monomer: synthesis of polymers through the polymerization of small molecules. ① addition polymerization reaction of monomer structural features: addition polymerization reaction of monomers is usually with a double bond or triple bond of unsaturated compounds, such as CH2 - CH2, CH2 a cH-c} nonyl = a CH2, CH2 a cHcl, etc. . ② polycondensation monomer structural characteristics: condensation reaction is usually with a single OH, a c (x) H, OH a NH. And other active hydrogen atoms or groups of compounds, such as il_, HCHO, Ho0c-R-c (x) H, / H0 BU _-R a 0H, H2N-R-CO0H, H (BU R-COOH, etc. .2 . chain: the composition of organic polymer of repeating structural units, such as a CH. a CHz I.3. polymerization degree: each polymer in the chain of repetitions, such as cH. a cH. the degree of polymerization. Second, synthetic organic polymers common type of response. ② by esterification condensation: O youth, please cherish this wealth of youth-specific taste of tea - Quyang one Middle School (26) Jing Lei ① pandan Where the chain of carbon atoms in the main chain of only two (no other atoms) of polymers, the monomer will be as one, will be closed to a half key, such as the seven c - CH ~ CH2 ~ monomer is CHC (X) CH. | two ■ i poison. I_ ¨ 1_ | ll ≮ # .. 'Jl Ao stack has not changed all day, but today's efforts can change the future trajectory. symmetrical structure, the monomer must into two, on hydrogenation in NH,herve leger toronto, one plus one in C_ 0H, that was a single 00 ¨ ¨ polymer body, such as the seven NH-cH an e-NHcH: mCH. c monomer is HeNCH2COOH and H2NCH2CH2CO0H . ③ middle section where the chain (not chain side) with the structure of the ester polymer, the monomer must have two, n0 101 from the disconnect, add in a 0H,tods shoes outlet, oxygen atom hydrogen atom, monomer derived polymer, such as a C, 0 - disconnect, add a C_ 0H, oxygen atom hydrogen atom, B ports have commercial polymer monomer,mulberry bags uk, such as n0 七 0-cH a cH a ( Bu monomer is HOC} {2 a cH. H and HooC (x] H. ④ polymer CH: The chain of cHz from formaldehyde, so the synthesis of monomers for the good performance of high heat-resistant resin is formed by the condensation of bisphenol should. trial, said the chemical reaction equation: --. 3 with the following structure of the peptide fragments, hydrolysis in the stomach,mulberry outlet, could not produce the amino acid is () a smile is not translated common language of mankind - in Tanghe County, Henan eight Middle School (3) classes Feifan trap CH and H: H ~ fL00 _ Bu a c (X) HH: H, 4. plastic ABS resin structure simple formula: seven c-C write a single form of ABS were --,--,--. 5 a new pyridine styrene-butadiene rubber elastic material structure is the short form: seven cH2 a cH = a cH-CH2 a CH2 ~ cH-cH , Il / the formation of its monomer may be --.
