General description
Poly(diallyldimethylammonium chloride) (PDDA) is a cationicpolyelectrolyte that easily ionizes when dissolved in water. This polymer iswidely used in the fields of waste-water treatment (as a flocculant) and the functionalizationof nanoparticles.
Application
Poly(diallyldimethylammonium chloride) can be used as a stabilizing agent in the synthesis of nanoparticles such as capped copper hexacyanoferrate (CuHCF) nanoparticles. The addition of PDDA protects the particles from aggregation and allows the synthesis of nanoparticles with controlled size and polydispersity. It can also be used to fabricate chemical and biological sensors. For example, PDDA-modified catalyst platforms can be used in the electrochemical detection of L-cysteine.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

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

May I know if this sample is atactic or does it have tacticity?
1 answer-
The tacticity is not defined or controlled for, so this product would be considered atactic.
