Poly (acrylic acid) (PAA
Polyacrylic acid
Poly(acrylic acid) is a synthetic high-molecular weight polymer of acrylic acid. The IUPAC name is poly(1-carboxyethylene). They may be homopolymers of acrylic acid, or crosslinked with an allyl ether of pentaerythritol, allyl ether of sucrose, or allyl ether of propylene. In a water sol…
Carbo-mer
In organic chemistry, a carbo-mer is an expanded molecule obtained by insertion of C₂ units into a given molecule. Carbo-mers differ from their templates in size but not in symmetry when each C–C single bond is replaced by an alkyne bond C-C≡C-C, each C=C double bond is replaced by an allene bond C=C=C=C, and each C≡C triple bond is replaced by C≡C-C≡C. The size of the carbo-mer continues to increa…

What is the difference between polyurethane and polycrylic?
Both polyurethane and polycrylic come in satin, gloss, and high-gloss sheens, so you can go as shiny as you’d like to emphasize your wood’s character and craftsmanship. However, note the following differences: 1 Oil-based polyurethane tends to dry with a slight yellowish tint, meaning you should only use it over wood that’s dark enough or warm enough to hide the yellow cast. 2 Water-based polyurethane dries completely clear, so you can use it over light woods like maple without concern for yellowing. 3 Polycrylic is generally said to dry clear, too, but as long as you’re careful with your application; it can take on a milky appearance if applied heavily over dark wood or paint.

Polyacrylonitrile (PAN) was first synthesized in 1930 by Hans Fikentscher and Claus Heuck in the Ludwigshafen works of the German chemical conglomerate IG Farben. However, as PAN is non- fusible, and did not dissolve in any of the industrial solvents being used at the time, further research into the material was halted.
What is a modacrylic?
Acrylics modified with halogen-containing comonomers are classified as modacrylics, which by definition contain more than PAN percentages between 35-85%. Incorporation of halogen groups increases the flame resistance of the fibre, which makes modacrylics suitable for the use in sleepwear, tents and blankets.
