In the process, the total amount of maleic anhydride fed to reaction is charged into a reactor and methyl vinyl ether is added thereto at a rate of 0.1-1.0equiv./ hr, preferably 0.1-0.3equiv./hr based on the aforementioned total amount of the maleic anhydride to enable molecular weight ...

The cyclic copolymer of divinyl ether and maleic anhydride was chosen for study. Intrinsic viscosities were determined in two solvents. The weight-average molecular weight was determined by light-scattering measurements and the number-average molecular weight was determined by osmometry. Results from a ...

The therapeutic efficiency of a drug is dependent on the availability at the target site at a concentration and frequency that maximises the therapeutic action and minimizes side-effects to the patient. Therapeutic drugs are often low-molecular weight molecules that result in non-specific distribution...
Influence of molecular weight and composition of copolymers of acrylic acid with maleic anhydride on their antiviral activity Journal Pharmaceutical Chemistry Journal Volume 12, Issue 7 , pp 913-915 Cover Date 1978-07-01 DOI 10.1007/BF00777638 Print ISSN 0091-150X Online ISSN 1573-9031 Publisher...
In this research work, synthesis and application of the poly (long chain α-olefin) with ultra high molecular weight, the copolymerization of long chain a-olefin and divinylbenzene (DVB) and the grafting copolymerization of homopoly(long chain α-olefin) and maleic anhydride by solution polymeriza...
(vinyl acetate and butyl acrylate) can improve the thermal properties of modified starches, which were further used in wood adhesive application [8]. Maleic anhydride was also employed as a functionalizing reagent to react with starch and to improve the shear strength of wood adhesives [9]. In...
(LDMS) with low molecular weight was synthesized using N, N-dimethylacrylamide; sodium p-styrene sulfonate; and maleic anhydride, which can maintain the performance of a drilling fluid gel system under high temperature. Unlike the conventional high-temperature-resistant polymer filtrate reducer, LDMS ...
