FAQs on Polymers

Polymers have thermal conductivities in the range of

Answer: 0.1 to 2 W/°C m.

Polymers have low molecular weight

Answer: There are various types of polymers with varying properties. Low Molecular Weight polymers have lower properties due to lack of chain entanglement and higher molecular mobility. Shorter chains have more end groups which increase free volume and molecular mobility which makes it easier for the polymer chains to respond to stresses.

Polymers have lowest solubility

Answer: Epoxy resin is a cross-linking polymer which has lowest solubility among them. It is characterized by hardening due to the generation of peroxide and also can also be modified for chemical resistance properties.

Polymers have molecular weight

Answer: The molecular weight of a polymer is expressed as the sum of the atomic weights of the constituent atoms (monomer residue) that comprise the molecule. It indicates the average length of the polymer chains.

Polymers have low density because of

Answer: Polymers have low density because of their branched chains. Branching can be described as the way in which a polymer is constructed from several components.
