What is the difference between multimer and polymer?

Apple  Follow

Monomers.

Amino acids are the monomers of proteins.

Monosaccharides are the monomers of polysaccharides.

A multimer is an aggregate of multiple molecules (aka monomers, as mono = one) that is held together with non-covalent bonds.

And multimerization is the process of assembling multimers of a given molecule.

Polymer, which is a series of monomers that are held together with covalent bonds, and which is assembled in a process known as polymerization.

So covalent bond matters!

Hello Dear,

The terms polymer and plastic are not the same. Plastic is a specific type of polymer comprised of a long chain of polymers. Polymers, on the other hand, are made up of uniform molecules that are smaller than plastic molecules.

Not all crosslinked polymers are thermoset materials. PEX, for example, is crosslinked polyethylene, but it is still thermoplastic. Thermoset materials develop their cross-links during the molding phase of production. Crosslinked thermoplastics develop their links during or shortly after polymerization. They go into molding already linked. No further links develop during molding.

I suspect we are into ‘semantics’ here - the meaning of words;

‘mixing’ means putting various things or various ingredients together in more or less random order, and placing, stirring or agitating to achieve more or less of a random distribution.

‘blending’ , means controlled mixing of ingredients under specified conditions to achieve desired qualities in the mix such as colour, texture, stiffness, aroma, viscosity; a word used to convey a sense of skilled elitism and ‘know-how’.

Copolymers are made from more than one monomer. Copolymers usually have better and/or different properties compared those of polymer made from one monomer and are more useful and have wider applications.

Well let me tell you a little story

During the oil crisis of the '70s, automakers discovered that plastics make cars more energy efficient by reducing weight. With that discovery, plastics began finding their way into automobile components such as bumpers, fenders, doors, safety and rear-quarter windows, headlight and side view mirror housings, trunk lids, hoods, grilles and wheel covers.

Auto makers choose plastic parts for their durability, corrosion resistance, toughness, ease of coloring and finishing, resiliency and light weight. Plastics reduced the weight of the average passenger car built in 1988 by 145 pounds. That saves millions of gallons of gas each year and will save the energy equivalent of 21 million barrels of oil over the average lifetime of those cars. By the 1993 model year, over 250 pounds of plastics were used in the average vehicle.

The oil crisis of the '70s also taught the airline industry the same lesson it taught automakers: lightweight plastics save fuel. The oil crunch forced aerospace companies to design aircraft that used less fuel. Translated, that meant more efficient engines, improved aerodynamics and reduced aircraft weight. It also meant a role for plastics.

Today, jet engine manufacturers are increasing their use of plastic materials for the same basic reasons: reliability, efficiency, fuel savings and improved performance. In the interiors and functional parts of aircraft, plastics are meeting more and more design requirements, and as the needs increase, new plastic materials are being created to meet them.

So the question that is polymer good certainly underwhelms the diaspora of the revolution that we are witnessing in our day today life. We are indeed living in Plastic or Polymer age.

Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack.
