Polymers have bonds
WebAnother type of polymer is the condensation polymer, which is a polymer made when two different monomers react together and release some other small molecule as a product.We have already seen an example of this in the formation of an amide bond: Here, H 2 O is released when the ends of the molecules react to form a polymer.. Related to … WebWhen polymers have higher conjugation length, the polymer will show high molecular weight due to the presence of the π bond because a high number of π bonds increases the …

WebSep 12, 2024 · A molecule from which a polymer is made is called a monomer. Each vinyl chloride monomer molecule contributes a CH 2 group joined to a CHCl unit by a single bond. This single bond is a remnant of the double bond which joined those groups in the vinyl chloride molecule. This is just what happens in an addition reaction of an alkene. WebA polymer is an organic material and the backbone of every organic material is a chain of carbon atoms. The carbon atom has four electrons in the outer shell. Each of these valence electrons can form a covalent bond to another carbon atom or to a foreign atom. The key to the polymer structure is that two carbon atoms can have up to three common ...
