Polylactic acid (PLA) was reactively functionalized with maleic anhydride (MA) and 2,5-bis( tert -butylperoxy)2,5-dimethylhexane (Luperox 101 or L101) using a twin screw extruder (TSE). The effects of functionality (grafted MA level) and/or number average molecular ...
The synthesis and application of environmentally friendly scale inhibitors attract increasing interest with the enaction of more and more stringent environmental protection policies. In this study, the intermediate N, N'-ethylenebismaleamic acid (EBMAA) was synthesized from maleic anhydride (MAH) and ...
[44] Microparticles of poly(L-lactic acid) (PLLA), poly(D,L-lactic acid) (PDLLA) and poly(glycolic acid) were successfully prepared by this process with pure CO2, CO2 with 1 wt% acetone cosolvent and chlorotrifluoromethane. Tom et al. were also the first to use RESS for the ...
4a, b). The maximum FS emission is observed at the FS doping rate of 0.87 wt%. Further increase of FS results in a decrease of the emission intensity, due to the notorious aggregation-caused quenching73,74. This means that CTE, just like conventional fluorescence, is able to undergo ...
The 100 wt% extraction efficiency for Zn(II) was obtained with (Cyanex 272 + diethyl phosphite). Quick and efficient extraction, with 100 wt% recovery of zinc and manganese, was obtained using DES (choline chloride [N2OH,1,1,1][Cl] : lactic acid 1:2, as well as choline chloride [...
2. It has been shown that to obtain condensation products with a relatively high concentration of alkenylsuccinic anhydride (up to 70% by wt.), the process is expediently conducted at 220–240°C, with a reaction time of 5 to 10 h, and a molar ratio of olefin to maleic anhydride from...
1,128,304. Ethylene/maleic anhydride/dicyclopentadiene terpolymers. FARBWERKE HOECHST A.G. 7 Feb., 1966 [5 Feb., 1965], No. 5244/66. Heading C3P. A high molecular weight terpolymer of ethylene, maleic anhydride and 0À01-2À5% by wt. of dicyclopentadiene is claimed. The terpolymer may...
98 grams of maleic anhydride were slurried with 50 grams of water and heated at 75° C. for 30 minutes in order to melt the maleic anhydride. The mixture was placed in a water bath, cooled to room temperature, and 68 grams of 30 wt% ammonium hydroxide was added dropwise to minimize ...
of maltodextrin, corn syrup solids, and mixtures thereof, wherein the number average molecular weight of the graft copolymer is about 100,000 or less, and the weight percent of the natural component in the graft copolymer is about 50 wt % or greater based on total weight of the graft ...
12.A cosmetic composition comprising the keratin hydrolyzate according to claim 1, wherein the composition comprises the keratin hydrolyzate in an amount of 0.002 to 0.4 wt % based on the active substance content. 13.A cosmetic composition conditioning hair treatment, comprising the keratin hydrolyzate...
