Summary Of: Polymers
polymers are not just limited to having predominantly carbon backbones... Polymers are studied in the fields of... scientists believed that polymers were clusters of small molecules... proposed that polymers consisted of long chains of atoms held together by covalent bonds... in the 1920s also demonstrated that polymers could be synthesized rationally from their constituent monomers... Most commercially important polymers today are entirely synthetic and produced in high volume on appropriately scaled organic synthetic techniques... Synthetic polymers today find application in nearly every industry and area of life... Polymers are widely used as adhesives and lubricants... Polymers such as poly... polymers have also been employed in the development of flexible polymer... polymers via laboratory synthetic methods... Many commercially important polymers are synthesized by chemical modification of naturally occurring polymers... Polymers that contain only a single type of monomer are known as homopolymers... while polymers containing a mixture of monomers are known as... Some biological polymers are composed of a variety of different but structurally related monomers... Special types of branched polymers include star polymers... polymers with two or three distinct blocks are called diblock copolymers and triblock copolymers... Synthetic polymers may consist of both crystalline and amorphous regions... Few synthetic polymers are entirely crystalline... The crystallinity of polymers is characterized by their degree of crystallinity... Polymers with a degree of crystallinity approaching zero or one will tend to be transparent... while polymers with intermediate degrees of crystallinity will tend to be opaque due to light scattering by... These are very important in many applications of polymers for films and membranes... polymers will decompose at high temperatures rather than melt... of a polymer substance is never defined because polymers will decompose before reaching theoretical boiling temperatures... which describes the temperature at which amorphous polymers undergo a second... concentrated solutions of polymers are far rarer than those of small molecules... dendritic polymers are not perfectly branched but share similar properties to dendrimers due to their high degree... The intermolecular forces in polymers can be affected by... The degradation of polymers to form smaller molecules may proceed by random scission or specific scission... are two polymers that are useful for their ability to degrade under aqueous conditions... A copolymer of these polymers is used for biomedical applications... in the water supply attacked vulnerable polymers in the plastic plumbing... Encyclodia Page On: Polymers
