Is Teflon a thermosetting polymer?
No, Teflon is not a thermosetting polymer. It is a thermoplastic polymer. Thermosetting polymers undergo a chemical reaction to form a stable, cross-linked structure when heated, while thermoplastic polymers soften when heated and harden when cooled. Teflon belongs to the latter category.
Role of ammonium persulphate in SDS-PAGE?
Ammonium persulphate is used in SDS-PAGE as a source of free radicals to initiate the polymerization of acrylamide and bisacrylamide monomers. When combined with a TEMED (Tetramethylethylenediamine) catalyst, it helps to create a crosslinked polyacrylamide gel matrix for separating proteins based on their size.
Does polythene melt when heated?
Because, it has no crosslinks therefore its molecules move more freely. On the other hand, some other polymers, such as Bakelite, are crosslinked and you cannot turn then into a liquid without breaking the covalent bond.
Why are some polymers stretchy while others are not?
The stretchiness of a polymer depends on its molecular structure. Polymers with long, flexible chains tend to be more stretchy because the chains can move past each other easily. In contrast, polymers with rigid or crosslinked structures are less stretchy because the chains are more constrained in their movement.
Anhydride with ethylene glycol versus phthalic anhydride with glycerol?
You get a polymer! When you have ethylene glycol react with phtalic anhydride in a basic sollution such as NaOH(aq) you'll get a linear polymer. When you have glycerol react with phtalic anhydride in the same way you'll get a crosslinked polymer. The important difference between glycerol and ethylene glycol is the amount of OH groups, and as we all know, the OH groups usually the group that reacts - particularly in the creation of polymers. So in this case your crosslinked polymer will be the glycerol as it has 3 OH groups. One in each end, allowing the molycule to connect with other molecules and create polymers, and one in the middle (connected to the 2nd Carbon Atom) allowing it to react with other polymers. I hope that sort of answers your question

What are the 3 kinds of clusters in tle?
In the context of technology-enhanced learning (TEL), the three kinds of clusters typically refer to content clusters, learner clusters, and context clusters. Content clusters group related educational resources or materials, learner clusters focus on the characteristics and needs of specific student groups, and context clusters consider the environmental and situational factors that influence learning experiences. Together, these clusters help in designing more effective and personalized learning experiences.
