What is the chemical formula for cellulose acetate butyrate?

Answer 1

I can e-mail you a picture of a CAB molocule, however, the structure and formula can take many forms as the ratio of butyral radicals to acetyl radicals varies with the properties you want in the finsihed polymer product. Steve srb12498@hvc.rr.com

Answer 2

For plastasol (PVC), I was taught that polymer is like spaghetti and plasticizer is like spaghetti sauce. The sauce lubricates the polymer chains and are allowed to flow over each other. There is probably different degrees of solubility of the polymer in the plastizer which will determine if the resuilt is opaque, hazy or transparent. PVC is typically mixed with plastisizer then heated to solvate.

This was taken from Wikipedia.

Plasticizers for plastics are additives, most commonly phthalates, that give hard plastics like PVC the desired flexibility and durability. They are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. Plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the "free volume"), and thus significantly lowering the glass transition temperature for the plastic and making it softer. For plastics such as PVC, the more plasticiser added, the lower its cold flex temperature will be. This means that it will be more flexible, though its strength and hardness will decrease as a result of it. Some plasticizers evaporate and tend to concentrate in an enclosed space; the "new car smell" is caused mostly by plasticizers evaporating from the car interior.

Answer 3

There is no chemical formula for cellulose but cellulose is made up of many molecules of glucose. And glucose's formula is C6H12O6. Hope that helps!

Answer 4

C6H10O5

Double check the above answer. I just looked at a bottle of it and there was no formula. It is used as a cation exchange resin.

Answer 5

Cellulose is an organic compound with the chemical formula (C6H10O5)n. it is a polysaccharide that is a chain of several hundred to over ten thousand glucose units.

Answer 6

The chemical formula for cellulose acetate butyrate is (C6H7O2(OCOCH3)x(OCOC4H7)y)n, where x and y represent the degree of substitution in the polymer chain and n is the number of repeating units.

Answer 7

Formula: CH3COO-
