Heptadecyl Acrylate (C17A)
Heptadecyl Acrylate (C17A) is an ester of Acrylic acid and is used as a raw material component in the synthesis of polymers. Heptadecyl Acrylate (C17A) is a monofunctional monomer with a characteristic high reactivity of acrylates and a long hydrophobic moiety. Heptadecyl Acrylate (C17A) forms homopolymers and copolymers. Copolymers of Heptadecyl Acrylate (C17A) can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as with acrylonitrile, maleic esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and with other monomers.
Heptadecyl Acrylate (C17A) is a very useful starting material for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds.
Product Type: Acrylate Monomer
Features & Benefits:
- Hydrophobicity
- Low Shrinkage
- Chemical resistance
- Adhesion
- Flexibility
- Low Tg
- Low volatility due to high molecular weight
- Weatherability
Characteristics:
- Low melting point (< – 100 °C): a) Benign handling; b) No tendency for crystalline domains
- High hydrophobicity: a) Improves solvency/compatibility with a base oil; b) Allows higher MMA ratios (cost-efficient)
- Branching: a) High thickening efficiency (compared to 2-EHMA, LMA, SMA); b) Shear stability (many branches, shear residuals do not increase wax content, low deposit forming tendency)
It is applied in the production of:
- HTHS and fuel-efficient lubricants

In order to prevent polymerization, Heptadecyl Acrylate (C17A) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, a storage stability of one year can be expected upon delivery. In order to minimize the likelihood of overstorage, the storage procedure should strictly follow the “first-in-first-out” principle. The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Storage tanks, pumps and pipes should be earthed.
