polymer meaning in kannada

There are also branched macromolecules with a main chain and side chains, in the case of polyethylene the side chains would be alkyl groups. Nylon and cellulose are polymers. The modulus is strongly dependent on temperature. In the case of chain-end scission, monomers are released and this process is referred to as unzipping or depolymerize . This increase in entropy scales with the number of particles (or moles) being mixed. Categories: Chemistry What does polümeer mean in English?

Tamil Meaning of Polymer Thanks for using this online dictionary, we have been helping millions of people improve their use of the TAMIL language with its free online services. Resins are usually mixtures of organic compounds.This article focuses on naturally occurring resins. iframe: { // FIXME: (temporary) - send ad requests only if PlusPopup is not shown In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. Pronounce word 150. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping. [39][40] These interactions tend to fix the individual chains more strongly in position and resist deformations and matrix breakup, both at higher stresses and higher temperatures. A uPVC, or unplasticized polyvinylchloride, is used for things such as pipes. [9][10] The modern concept of polymers as covalently bonded macromolecular structures was proposed in 1920 by Hermann Staudinger,[11] who spent the next decade finding experimental evidence for this hypothesis.[12]. A pipe has no plasticizers in it, because it needs to remain strong and heat-resistant. { bidder: 'openx', params: { unit: '539971066', delDomain: 'idm-d.openx.net' }}, Dipole bonding is not as strong as hydrogen bonding, so a polyester's melting point and strength are lower than Kevlar's (Twaron), but polyesters have greater flexibility.

This has led to many applications in the field of organic electronics. Because of this work, Staudinger was awarded the Nobel Prize in 1953.

polymer meaning in kannada
There are also branched macromolecules with a main chain and side chains, in the case of polyethylene the side chains would be alkyl groups. Nylon and cellulose are polymers. The modulus is strongly dependent on temperature. In the case of chain-end scission, monomers are released and this process is referred to as unzipping or depolymerize . This increase in entropy scales with the number of particles (or moles) being mixed. Categories: Chemistry What does polümeer mean in English?

This change in properties is often the result of bond breaking in the polymer backbone (chain scission) which may occur at the chain ends or at random positions in the chain.

Tamil Meaning of Polymer Thanks for using this online dictionary, we have been helping millions of people improve their use of the TAMIL language with its free online services. Resins are usually mixtures of organic compounds.This article focuses on naturally occurring resins. iframe: { // FIXME: (temporary) - send ad requests only if PlusPopup is not shown In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. Pronounce word 150. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping. [39][40] These interactions tend to fix the individual chains more strongly in position and resist deformations and matrix breakup, both at higher stresses and higher temperatures. A uPVC, or unplasticized polyvinylchloride, is used for things such as pipes. [9][10] The modern concept of polymers as covalently bonded macromolecular structures was proposed in 1920 by Hermann Staudinger,[11] who spent the next decade finding experimental evidence for this hypothesis.[12]. A pipe has no plasticizers in it, because it needs to remain strong and heat-resistant. { bidder: 'openx', params: { unit: '539971066', delDomain: 'idm-d.openx.net' }}, Dipole bonding is not as strong as hydrogen bonding, so a polyester's melting point and strength are lower than Kevlar's (Twaron), but polyesters have greater flexibility. [53][54] This is very important in applications that rely upon a polymer's physical strength or durability. { bidder: 'openx', params: { unit: '541042770', delDomain: 'idm-d.openx.net' }}, In dilute solutions, the properties of the polymer are characterized by the interaction between the solvent and the polymer. {\displaystyle M_{w}} userSync: { Attack of the acetal joint occurred because of faulty molding, leading to cracking along the threads of the fitting where there is stress concentration. bidders: '*', { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_btmslot_300x250' }}, Polymers with microcrystalline regions are generally tougher (can be bent more without breaking) and more impact-resistant than totally amorphous polymers.

This has led to many applications in the field of organic electronics. Because of this work, Staudinger was awarded the Nobel Prize in 1953.
