In addition to the type number and sequential arrangement of monomers along the chain the spatial arrangement of substituent groups is also important in determining properties.
Drawing vinyl monomers.
The carbon backbone is made out of carbon atoms bonded covalently with each other.
Only in this case the.
This problem has been solved.
For the following polymer show transcribed image text.
The process is similar to pulling apart the yarn thread by thread.
Most monomers of this kind including propylene vinyl chloride styrene acrylonitrile and acrylic esters prefer to join in a head to tail fashion with some randomness occurring from time to time.
It is located in the carbon backbone of the polymer.

There are no double bonds found in the carbon backbone since the double bond is broken in order to make the monomer reactive in the polymerization process.
Basf combines 90 years of experience in the development of high quality functional vinyl monomers including vinyl ethers and n vinyl compounds with state of the art know how and technology.
