A single macromolecule will not fit into one of those crystallites, so it bends over itself and can extend over several w.billmsyer.

Chang – – pages Class 3. In other polymers, such as PVC, the degree of crystallinity is much lower and it is more reasonable to consider it as two-phase systems, an ordered, crystalline, embedded in an amorphous matrix. Brown – – pages.

The sigma links also known as simple links of carbon can rotate with some freedom, but two enantiomers can not be overcome no matter how much this link turns, but it is necessary to break the links to relocate them and then superimpose them. Chromogenic peptides in the Folin Lowry colorimetric protein determination by Shao-chia Chou – – pages. In a molecule in which only carbon atoms include the elements of the main chain provide a three-dimensional arrangement in the form of tetrahedra, this can be represented in several ways, one of them is the projection of Natta developed by Giulio Natta in which the zigzag carbons of the main chain are in the plane of the paper.

Source Isotactic polymers A polymer with a stereoregular characteristic, in other words the functional group is located only on one side of the monomer, that is, on only one axis of the three-dimensional plane.

Gerebtzoff – – pages. Sabine – – pages. The proportion or percentage of crystalline areas can be very high, as in polyethylene, in nylon and in cellulose. The density of a crystalline polymer is greater than that of an amorphous polymer of the same material and molecular weight, since the chains of the crystalline structure are more packed.


Lee, Ckencia Lee – – 32 pages. A chemical model is very useful to study this type of links. In the crystalline solids, the molecules are arranged in the three dimensions. Coal–typology, physics, chemistry, constitution by Dirk Willem Krevelen – – pages.

The semicrystalline polymers have analogy with biphasic metallic alloys that is to say they present ordering regions and regions in which the polymer is amorphous.

Regions of two classes are distinguished: Atactic polymers In atactic polymers, the substituents are distributed randomly along the chain of the macromolecule.

The most direct test is provided by X-ray diffraction studies.
