If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Butyl acrylate undergoes radical copolymerization with benzoxazine containing a vinyl group to afford copolymers.[1] Heck coupling reactions of aryl bromides with n-butyl acrylate mediated by phosphine-imidazolium salt have been reported.[2] Copolymerization of styrene and n-butyl acrylate by ATRP catalyzed by CuBr/4,4′-di(5-nonyl)-2,2′-bipyridine has been described.[3]
Application
- An electrolyte additive in lithium-ion batteries to improve their low-temperature performance. The addition of BA to the electrolyte led to a significant improvement in the low-temperature performance of the battery, including enhanced ionic conductivity and improved rate capability.
- A monomer to synthesize a shape memory polymer network that contains magnetic nanoparticles for various applications, including actuators and biomedical devices.
- A monomer for the preparation of a polymeric semiconductor with intrinsically stretchable properties. This polymer material is used as a component in field-effect transistor applications.
- Poly(butyl acrylate) particles.[4]
- Poly(butyl acrylate-b-acrylic acid) block copolymer.[5]
- Amphiphilic charged diblock copolymers poly(butyl acrylate)-b-poly(acrylic acid).[6]
- Poly(n-butyl acrylate), via atom transfer radical polymerization (ATRP) of n-butyl acrylate in the presence of CuIBr/4,4′-di(5-nonyl)-2,2′-bipyridine (catalyst).[1]

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
