Polycarbonate,LCP,biopol,conducting polymer,electroluminescent polymer

Polycarbonate polymers are used for making goggles because It has high durability It has high impact resistance It has high resistance to water It has high optical clarity

Kevlar is a Glass fiber Carbon fiber aramid fiber metallic fiber

The chemical composition of Kevlar is Para polyphenylene terephthalene polyphenyl para terephthalamide poly paraphenylene terephthalamide poly terephthalene paraphenylene

If a liquid crystalline polymer exhibits liquid crystalline phase in solution ,it is known as Thermotropic Lyotropic Mesotropic sesotropic

If a liquid crystalline polymer exhibits liquid crystalline phase in melt,it is known as Thermotropic Lyotropic Mesotropic sesotropic

Kevlar isa Smectic lyotropc LCP nematic lyotropc LCP Smectic thermotropic LCP nematic thermotropic LCP

Thermal stability of kevlar is due to Amide group Aramide ring structure Long chain All of these

The disprsed phase in fibre reinforced plastic can be Glass fibre Carbon fibre Aramid fibre All of these

First reported electroluminescent polymer is Polyamide Poly-phenylene –vinylene polymer Polyacetylene Poly vinyl chloride

In a polymer light emmiting diode ,Indium –tin-oxide is commanly used as Anode material Cathode material For both anode and cathode For neither anode nor cathode

Biopol is the commercial name of Polyhydroxybutyrate Polyhydroxyvalarate Polyhydroxybutyrate-hydroxyvalarate Hydroxybutyrate-hydroxyvalarate

Polyacetylene is doped with----to increase conductivity Germanium Silicon Iodine benzene

Conductivity of polymers is observed due to P dopingof ICP N dopingof ICP Metallic fibre blending of ECP Allof these

On polymer backbone ,N doping creates Positive charge Negative charge Neutral charge All of these
