What is the name of the chemical reaction which combines monomers to make polymers?
Simply - polymerization. However, this is usually addition polymerization but not always. Nylon is formed by condensation polymerization and the polymers used to make waterbased latex paints is usually called emulsion polymerization.
What is concentration polymerization?
If you're talking about condensation polymerization, it is a reaction in which monomers join together to give a long chain molecule (the polymer) and a small molecule, usually water or hydrochloric acid, like Nylon.
What is bulk polymerization?
Bulk polymerization is a method of polymerizing monomers where they are all polymerized in a single phase without a solvent. It involves mixing the monomers together and initiating the reaction to form a polymer within the same reaction vessel. This process is used for producing polymers with high molecular weight and purity.
Compute the degree of polymerization of polystyrene?
The degree of polymerization(n) is the ratio between Molecular weight(M) and the molar mass of the repeating unit in a polymer(m). M=n*m The molar mass(m) of the monomer (styrene) is 104.15 grams/mol if you are given a Molecular weight, just devide by m, and you've got it!
How Degree of polymerization affect to the crystallinity?
A higher degree of polymerization generally leads to higher crystallinity in polymers. Longer polymer chains can pack together more closely in an organized manner, increasing the likelihood of crystalline regions forming. This results in a higher degree of ordered molecular structure, leading to increased crystallinity in the polymer.

What is the molecular weight of Chlorinated polyvinyl chloride resin?
Molecular weight of a polymer depends rather on it's degree of polymerization (chain length) than on it's composition. Typical polymer molecular weights are in the range of 1000 to 1000 000 and beyond.
What is the name for a reaction that links monomers to form a food chain?
The process of linking monomers to form a food chain is known as polymerization. This involves the chemical reaction that combines monomers to form larger molecular structures called polymers, such as proteins, carbohydrates, and nucleic acids.
What is the suitable organic solvent for polystyrene?
It depends on the molecular weight and 3-D structure of the polymer.
What is the molecular weight of Dextrin?
The average molecular weight of dextrin can vary depending on the degree of polymerization and branching. Typically, dextrin has a molecular weight ranging from 500 to 5,000 g/mol.

Longer polymer chains can pack together more closely in an organized manner, increasing the likelihood of crystalline regions forming. This results in a higher degree of ordered molecular structure, leading to increased crystallinity in the polymer.
Is polypropylene a solid?
Any substance with a sufficiently large average molecular weight to be called "polypropylene" under normal circumstances is a solid at standard temperature and pressure. However, note that some hydrocarbons, such as hexenes, that could be formed by condensing small numbers of polypropylene molecules, are not solids at standard temperature and pressure.
What is the average molecular weight of PVC?
62.5 * length of chain ( num of moluclar of vcm )!! think that
What are some physical properties of a plastic bag?
Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip. Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene
