As we all know, the initiator fragment of the polymerization can be introduced to the polymer as the end group, and the same vegetable complex can present different end groups due to different initiators(brown fused alumina price). It has been found that they have different rheological properties in a certain molecular weight range(brown aluminum oxide 250 grit). The molecular motion behavior of larger size polymers can be described by the "bond" motion.

In fact, polymer is a kind of mixture of homologous polymers with the same chemical composition (same chain structure) and different molecular chain length (different chain number of each molecule). Generally, polymers are linear(green silicon carbide). Long chains of molecules can be curved into groups or extended into straight lines, which depends on the flexibility and external conditions of the molecule itself(brown fused alumina suppliers).


In addition, if the structure and content of the end group can be determined accurately, it can be used to obtain the information of polymerization mechanism, molecular weight(silicon carbide abrasive). For example, the main chain of poly quotient and Jiaxing polymers contains oxygen atoms, the main chain of poly acid amine polymers contains ammonia atoms, and the main chain of poly floating polymers contains sulfur atoms(brown fused alumina 60 grit).


The higher the degree of polymerization is, the less the weight of the end group is, and the less the effect on the properties of the polymer material is(white fused alumina). Obviously, the effect of the end group is different from that of the side group, which is greatly influenced by the degree of the conformation(brown fused alumina factory). Polymer is a kind of compound composed of many macromolecules connected by small monomers. 


Bonding structure refers to the connection mode of structural unit in polymer chain, which is also one of the important factors affecting the performance(black silicon carbide). The bonding structure of dienes is more complex. For example, butadiene is polymerized and inspected in the process of polymerization(aluminum oxide grit). Many experiments have proved that most of the products of free radical or ionic polymerization are head to tail bonding. 


In polycondensation and ring opening polymerization, the bonding mode of structural unit is generally clear, but in the process of addition polymerization, the bonding mode of monomer can be different(white aluminum oxide). For example, the possible bonding modes of monomers (CH, - Chr) in the process of cheap combination are head end (tail end) bonding: it is also possible that there are two kinds of random bonding at the same time(white fused alumina oxide mfg).


For vinyl polymers, although the head-end bonding is dominant, the existence of the head-end bonding structure cannot be ruled out(aluminum oxide abrasive). For example, there is a small amount of head-end bonding in poly (ethylene paraacid); the content of head-end bonding is 8% ~ 12% in vinylidene chloride marriage(wholesale brown fused alumina); the content of head-end bonding in PVC can be as high as 16%, branching degree and other structural factors.


The following two products may have different bonding modes of head tail and head head head for addition polymerization and encapsulation, as well as various configurations of CIS and trans for addition polymerization(brown aluminium oxide). There are diene monomers with substituents on the second (or third) carbon atom(brown fused aluminum oxide factory). For example, there are two kinds of bonding modes: of course, head tail and head head head.
