Which Type Of Polymer Contains A Benzene Ring Pendant Group. This increases T g. As in polystyrene the presence of benzene ring increases the T g see Fig. An arotinoid is any of a group of synthetic derivatives of a retinoid which contains a benzene ring. Individual chains contain sequences of six aliphatic groups COOCH2 CH 2 OCO.
In polypropylene there is no benzene ring that leads to lower T g value Fig. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring five of which are bonded to. A group attached to the polymer backbone and present in the repeating unit is called a pendant group. Contains compounds with benzene rings substituted with amino- alkylamino- amide- phenylhydrazine- or phenylazo- groups. Contains both aromatic and non-aromatic azo compounds. The PET fibers have a rigid benzene ring in its backbone.
A group attached to the polymer backbone and present in the repeating unit is called a pendant group.
Phenyl groups are closely related to benzene and can be viewed as a benzene ring minus a hydrogen which may be replaced by some other element or compound to serve as a functional group. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring five of which are bonded to. Bulky pendant groups such as a benzene ring can catch on neighboring chains like a fish hook and restrict rotational freedom. Contains nitroaromatic and secondary nitroalkyl compounds. In organic chemistry the phenyl group or phenyl ring is a cyclic group of atoms with the formula C6H5. The PET fibers have a rigid benzene ring in its backbone.
