25153-40-6 Usage
Description
Methyl vinyl ether/maleic acid copolymer, also known as Poly(methyl vinyl ether-alt-maleic acid) (PMVEMA), is a hydrophilic and biocompatible polymer with bioadhesive properties. It is an acidic polymer that can enhance the stability and zeta potential of polyaniline (PANI) solutions. PMVEMA is a white to light cream powder in appearance.
Uses
1. Detergent Industry:
Methyl vinyl ether/maleic acid copolymer is used as a detergent builder for its ability to improve the cleaning efficiency and effectiveness of detergent formulations.
2. Medical and Food Packaging Industry:
PMVEMA can be cross-linked with cellulose whiskers for the formation of nanocomposite films, which have potential applications in the medical and food packaging industries due to their enhanced properties.
3. Drug Delivery Systems:
Methyl vinyl ether/maleic acid copolymer is used as a component in drug delivery systems, where it can be conjugated with polyethylene glycol (PEG) to form hydrogels. These hydrogels are beneficial for controlled and sustained release of therapeutic agents, improving the overall efficacy and safety of drug administration.
Check Digit Verification of cas no
The CAS Registry Mumber 25153-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25153-40:
(7*2)+(6*5)+(5*1)+(4*5)+(3*3)+(2*4)+(1*0)=86
86 % 10 = 6
So 25153-40-6 is a valid CAS Registry Number.
