is used in the manufacture of plasticizers such as PVC.
Since the N-terminus of every amino acid will react with acetic anhydride, only amino acids that acquire two or more acetyl groups are likely to react with anhydrides when they are found in a polypeptide chain.
Being less limited by spatial constraints it is expected that smaller anhydrides will provide better mapping of protein surfaces, and therefore only the acetic anhydride data are reported here.
Films of the epoxidized resin were cured at an elevated temperature with either diamine or anhydride crosslinking agents.

APPLICATION: With a long useful life in the emulsion form, ethyl oleate succinic anhydride
could become one of the preferred sizing chemicals in papermaking.
Some ASA's are made by heating an alpha olefin with maleic anhydride
, For other ASA's, the alpha olefin is first isomerized to a mixture of linear internal olefins, which is then combined with maleic anhydride
to make a mixture of ASA's having a lower pour point than an ASA made directly from an alpha olefin.
It can be assumed that the terminal anhydrides
groups on PET chain ends are thermally stable until 280 [degrees] C, even if this temperature is kept for 25 minutes.
Two saturated anhydrides
, HHPA (hexahydrophthalic anhydride
) and MeHHPA (methylhexahydrophthalic anhydride
) provide excellent electrical properties and good weatherability.
LONDON -- Global production and consumption of Maleic Anhydride
(MA) in 2008 were approximately 1.
The company has carried its technology a logical step forward with Luchem HA-B18, made by pre-reacting HA-R100 with a polyolefin resin--in this case an octadecene-maleic anhydride
copolymer, similar to a maleated PP.
Offers formulated liquid amines, polyamides, anhydrides
, and Lewis acids, both filled and unfilled.
Also available is the company's Lekutherm Hardener H, hexahydrophthalic anhydride
The researchers make the strength-giving component by reacting trimellitic anhydride
with an amino acid such as glycine.
Vanamid and Polydride products comprise a full line of amine and anhydride
curing agents for use with the company's Vanoxy epoxy resins.
