Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia, US.The generic name "spandex", which is an anagram of the wor...
while copolymers are made from two separate types of monomer. This change in the structure gives these two materials slightly different properties. Specifically, the copolymer version is less porous for increased performance in wet and high-temperature environments....
Block copolymer 2.What is a homopolymer? Homo polymer is a type of polypropylene which is a corrosion resistant material and has high tensile strength and stiffness at high temperatures. Homopolymer is a light weight, highly strain resistant and low moisture absorption material. It also provides gr...
