Fire and heat resistant laminating resins based on maleimido substituted aromatic cyclotriphosphazene polymer [PDF]

open access: yes, 1987
4-Aminophenoxy cyclotriphosphazenes are reacted with maleic anhydride to produce maleamic acids which are converted to the maleimides. The maleimides are polymerized. By selection of starting materials (e.g., hexakis amino or trisaminophenoxy trisphenoxy

Design, Synthesis, and Anticancer Activity Study of several New Schiff Base Imidyl Sulfa Drug Derivatives based on N-(Sulfamethoxazole-4-yl)-4-Aminomethylbenzylidene

open access: yesIraqi Journal of Pharmaceutical Sciences
In this research, a series of new (Schiff base imidly sulfa drug) derivatives were designed and synthesized via many steps. In the first step, a sulfa drug (sulfamethoxazole) was chosen as a bioactive starting material and introduced in a condensation ...

High Density Polyethylene/Ground Tire Rubber Composites Compatibilized by Dicumyl Peroxide

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT In this study, the thermal behavior of dicumyl peroxide (DCP) was first evaluated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which confirmed a peak decomposition temperature around 172°C, highlighting its incompatibility with standard melt‐mixing techniques for most polyolefins. To overcome this limitation,

Copdymers of Maleic Anhydride

open access: yesKobunshi Kagaku, 1970
メタクリル酸グリシジルと無水マレイン酸とのラジカル共重合をアセトンまたはジオキサン中で40°または50℃で行なった。モノマー組成とコポリマー組成の関係はpenultimate effectを考えれば合理的に説明できる。モノマー反応性比は50℃では4.2 (rG) および0 (rM=rM′=1/rG′) であり, 40℃ては4.5 (rG) および0 (rM=rM′=1/rG′) である。コポリマーはエポキシ基および無水マレイン酸基の反応で不溶性に変わる。

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

High performance mixed bisimide resins and composites based thereon [PDF]

open access: yes, 1986
Mixtures of bismaleimide/biscitraconirnide resins produces materials which have better handling, processing or mechanical and thermal properties, particularly in graphite composites, than materials made with the individual resins. The mechanical strength
