POLYSTYRENE-B-POLY(4-VINYL PYRIDINE) is a block copolymer comprising of polystyrene as the backbone and poly(4-vinyl pyridine) as the side chain. This copolymer exhibits unique properties due to the presence of two different polymer segments. Polystyrene provides rigidity and mechanical strength to the material, while poly(4-vinyl pyridine) contributes to its chemical reactivity and affinity to specific substances. This copolymer is commonly used in applications such as adhesives, coatings, and as a compatibilizer in polymer blends. Its specific properties make it useful in a wide range of industries, including electronics, biomedical, and packaging.
Check Digit Verification of cas no
The CAS Registry Mumber 26222-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,2 and 2 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 26222-40: (7*2)+(6*6)+(5*2)+(4*2)+(3*2)+(2*4)+(1*0)=82 82 % 10 = 2 So 26222-40-2 is a valid CAS Registry Number.
