Foam peanuts (made of expanded polystyrene) The inner structure of a foam peanut, magnified 390× on an SEM. Foam peanuts, also known as foam popcorn, packing peanuts, or packing noodles, are a common loose-fill packaging and cushioning material used to prevent damage to fragile objects during shipping.
In polymer chemistry, polymerisation inhibitors (US: polymerization inhibitors) are chemical compounds added to monomers to prevent their self-polymerisation. Unsaturated monomers such as acrylates , vinyl chloride , butadiene and styrene require inhibitors for both processing and safe transport and storage.
Eating nuts, popcorn, or seeds does not increase the risk of diverticulitis. [356] These foods may actually have a protective effect. [357] Eating less than an hour before swimming does not significantly increase the risk of experiencing muscle cramps, and does not increase the risk of drowning.

Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (CH 2 CHCN) n. [2] Almost all PAN resins are copolymers with acrylonitrile as the main monomer .
I feel like the sensation of coating my entire hand and forearm—once I got so deep into my popcorn that I had to start digging for more—would probably cancel out any cleanliness bonus that the ...
Polymer morphology is a microscale property that is largely dictated by the amorphous or crystalline portions of the polymer chains and their influence on each other. Microscopy techniques are especially useful in determining these microscale properties, as the domains created by the polymer morphology are large enough to be viewed using modern ...
A large amount of acrylonitrile (approximately 6500 tons) leaked from an industrial polymer plant owned by Aksa Akrilik after the violent 17th August 1999 earthquake in Turkey. Over 5000 people were affected and the exposed animals had died. [32] The leak was only noticed by the company 8 hours after the incident.
