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...
1.0 wt% of benzoyl peroxide initiator was added to the mixture and it was refluxed under isothermal conditions for 24 h. After in-situ polymerization, the mixture was sonicated for 15 min and poured into a clean glass Petri dish, and dried at room temperature for 5 h. The FDU-12-methacry...
The values of Kare of higher order than the conventional CT systems, for instance, styrene-maleic anhydride has 0.34 in hexane. 10 BOT may act as an electron-donor and DEB as an electron-acceptor, since the ionization potential ofTP and PA is 8.54 eV11 and 9.15eV, 12 respectively. The ...
PRODUCTION OF HIGH-MOLECULAR-WEIGHT ALIPHATIC POLYESTER POLYMER, AND HIGH-MOLECULAR-WEIGHT ALIPHATIC POLYESTER POLYMER PROBLEM TO BE SOLVED: To provide a process for producing a biodegradable high-mol.-wt. aliphatic polyester polymer moldable into films or fibers. T Ikuo,高橋 郁夫,K Kenji,... 被...
High molecular weight polyisobutylene (PIB) was modified by a mild and facile melt‐mixing process with thermoplastic polyurethane elastomer (TPU) in the presence of a compatibilizer, i.e., polypropylene‐g‐maleic anhydride (PP‐g‐MAH). Scanning electron microscopy (SEM) in combination with ...
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 ...
aromatic monomers, especially styrene, with one or more additional unsaturated, copolymerizable monomers, particularly the ethylenically unsaturated nitrile monomers (such as acrylonitrile and/or methacrylonitrile), maleic anhydride, alkyl methacrylate, N-substituted maleimide or other polymerizable comonomers...
of Great Lakes Chemical Corp., the molecular weight of the polybromostyrenes has typically been adjusted using 1-dodecanthiol as a chain transfer agent added during polymerization. For a period of time a homopolymer of mixed mono-, di- and tribromostyrenes having about 60 wt % bromine and ...
