3) were therefore attributed to cellulose reaction per anhydrides and amides, (6), (12) as represented within Fig.
The anhydrides were predicted to react with the amino acid side chains of serine, threonine, arginine, asparagine, lysine, histidine, tyrosine, glutamine, and cysteine.
In this paper we study the mechanism and kinetics of epoxy resins cured via anhydrides on model reactions.
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.
One of the most frequently used monomers is maleic anhydride (MA), owing to the high reactivity of anhydride group in successive reactions.
* Two saturated anhydrides, HHPA (hexahydrophthalic anhydride) and MeHHPA (methylhexahydrophthalic anhydride) provide excellent electrical properties and good weatherability.
Abstract Isopropylthioxanthone is a popular cosynergist for Type II and three-component photoinitiators used to photopolymerize ultraviolet (UV) curable coatings and can be used in the presence of maleic anhydride derivatives to efficiently cure coatings used in numerous applications.
However, it is known that in the absence of catalyst the anhydrides do not react directly with the epoxy group.
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.
Notice that those reactions consume -OH chain ends and anhydrides. Effectively, a progressive increase followed by a decrease of the normalized absorption band at about 1785 [cm.sup.-1], characteristic of anhydride grafting, is observed in FT-IR after the addition of the acid chloride for the melt mixed samples as presented in Fig.
These anhydrides find use in filament winding, pultrusion, prepreg manufacture, potting and encapsulation, powder coating, and vacuum-pressure impregnation.
Compared with aromatic amines and anhydrides, CE's yield higher HDT's (355-392 F) with no compromise of mechanical strength, lower water absorption, and lower dielectric constant (3.0-3.1) and dissipation factor (0.008-0.009).
Supplies anhydrides and polyanhydrides for curing epoxy resins.
