http://www.ichacha.net/step%20growth%20polymerization.html 網頁We report on the marked similarity between the self-assembly of metal nanoparticles and reaction-controlled step-growth polymerization. The nanoparticles act as multifunctional monomer units, which form reversible, noncovalent bonds at specific bond angles and organize themselves into a colloidal polymer.

Let's take a look at the step growth polymerization of two monomers, terephthaloyl chloride and ethylene glycol, to make a polyester called poly (ethylene terephthalate). The first thing that happens is that the two monomers will react to form a dimer. Sounds simple enough.
網頁Copolymers and polymer blends. When a single monomer is polymerized into a macromolecule, the product is called a homopolymer—as shown in Figure 3A, with polyvinyl chloride as the example. Copolymers, on the other hand, are made from two or more monomers. Procedures have been developed to make copolymers in which the repeating …
網頁2015年1月1日 · Step-growth polymerizations, in general, may be broken down into two categories – (i) step polycondensation and (ii) step polyaddition. As the name implies, step polycondensation refers to the formation of polymers by stepwise condensation reaction of bifunctional or polyfunctional monomers with elimination of a small-molecule byproduct at … dying light 2 piratedhttp://www.scidict.org/items/Step%20growth.html crystal reports using like in formula網頁2024年3月8日 · Condensation polymerization or step-growth polymerization. Addition or Chain Growth Polymerization When the same or different monomer molecules (unsaturated compounds) are successively added together on a large scale to form a polymer, this type of polymerization is known as addition or chain-growth polymerization. crystal reports v14在華萊士·卡羅瑟斯有關聚合反應類別的分類當中，有一種透過單體或單體鏈不斷進行縮合作用而形成聚合物鏈的分類法，稱作縮合聚合作用。這過程偶爾稱作逐步增長聚合（Step-growth polymerization），但其實兩者的考慮點並不相同。 兩者最大的分別在於加成聚合及縮合聚合是以生成物的角度去考慮，而逐步增 … 查看更多內容 縮合反應（condensation reaction）是化學反應的一種，當中兩個分子透過官能基的變化結合成一個新的分子，過程中有細小的分子失去。 如所失去的小分子為水，這個過程則稱作脫水反應。其他常見的小分子包括氯化氫 查看更多內容 很多縮合反應的機理均跟從亲核酰基取代反应或羟醛缩合的路徑進行。其他的縮合反應，如酮醇缩合等則須透過如自由基或單電子轉移（single electron transfer）的引發進行。 查看更多內容 • 同化作用 • 水解反應 • 縮合聚合反應 • 人名反應 查看更多內容 這一反應類別是製造形形色色的聚合物的基礎，當中如尼龍及聚酯等，不同類型的縮合聚合物及多樣的环氧树脂類化合物。此外，它也是實驗室中製備矽酸鹽及多磷酸鹽（polyphosphates） … 查看更多內容 dying light 2 player stash網頁Step-growth polymerization typically takes place between monomers containing functional groups that react in high yield to form new functionalities.
