Why does thiokol rubber has very bad odor?
Thiokol rubber, a type of synthetic rubber made from polysulfide polymers, has a strong, unpleasant odor primarily due to the presence of sulfur compounds used in its production. These sulfur compounds can emit volatile organic compounds (VOCs) that contribute to its distinctive smell. Additionally, the curing agents and additives used in the manufacturing process can further intensify the odor. Despite its odor, thiokol rubber is valued for its unique properties, including chemical resistance and flexibility.
How is the thiokol discovered?
Thiokol was discovered in 1929 after a surprising and unplanned reaction between sodium polysulfide and ethylene dichloride.
Why rubber have the same empirical formula as its monomer?
An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
What is the monomer unit of neoprene?
The monomer unit of neoprene is chloroprene, also known as 2-chlorobutadiene. It is a diene compound with the chemical formula C4H5Cl. When polymerized, chloroprene forms the synthetic rubber known as neoprene, which is valued for its resistance to oil, heat, and weathering.
Is a triglyceride a monomer or polymer?
monomer
How do you prepare thiokol rubber?
we will prepare thiokol rubber from 1,2 dichloroethane and sodiumpolysulphide.The reaction is:cl-CH2-CH2-cl + Na-S-S-Na + cl-CH2-CH2-cl--------------> -----(----CH2-CH2-S-S-CH2-CH2----)n--------

What is the population of Thiokol?
Thiokol's population is 15,000.
When was Thiokol created?
Thiokol was created on 1929-12-05.
When did Thiokol-Woodbine Explosion happen?
Thiokol-Woodbine Explosion happened on 1971-02-03.
Who made the O-rings for the Challenger?
The O-rings for the Space Shuttle Challenger were manufactured by Morton Thiokol.

An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
What type of bond does rubber have?
Rubber typically has a covalent bond structure. This is because rubber is made of long chains of repeated monomer units (usually isoprene), which are connected through strong covalent bonds within the polymer structure.
What is the monomer unit of neoprene?
The monomer unit of neoprene is chloroprene, also known as 2-chlorobutadiene. It is a diene compound with the chemical formula C4H5Cl. When polymerized, chloroprene forms the synthetic rubber known as neoprene, which is valued for its resistance to oil, heat, and weathering.
What epdm stand for?
EPDM or Ethylene Propylene Diene Monomer is a specific type of synthetic rubber. But it’s not the same rubber found in car tires or toy balls. EPDM roofing system has the ability to maintain elasticity over time even if it is exposed to extreme temperatures and UV-rays and can withstand water ponding such as those found on commercial and industrial roofs.
What rubber don't melt?
Rubber that doesn't melt is typically referred to as "thermoset rubber." Unlike thermoplastic rubber, which can melt and be reshaped when heated, thermoset rubber undergoes a chemical change during the curing process, making it heat-resistant and stable at high temperatures. Examples include silicone rubber and EPDM (ethylene propylene diene monomer) rubber, which maintain their integrity under heat and do not melt.
