Select up to 4 products. The synthesis in bulk results in high molecular weights up to m w 2 500 000 g mol. Briefly 0 25 g of naalg. Poly vinyl caprolactam pnvcl is one of the most important thermoresponsive polymers because it is similar to poly n isopropyl acrylamide.

New cationic linear copolymers and hydrogels of n vinyl caprolactam and n acryloyl n ethyl piperazine. Synthesis reactivity influence of external stimuli on the lcst and swelling properties. However reported with a high dispersity đ the synthesis in water and water containing systems also results in high molecular weight pnvcl but the size exclusion chromatograms show broad distributions bimodal distributions and second distributions as shoulders indicate a poor control of polymerization. Caprolactam was first described in the late 1800s when it was prepared by the cyclization of ε aminocaproic acid the product of the hydrolysis of caprolactam.

Synthesis of novel temperature and ph sensitive aba triblock copolymers p deaema co meo2ma co oegma b peg b p deaema co meo2ma co oegma. Please select more than one item to compare. Need larger quantities for your development manufacturing or research applications. The use of pnvcl instead of pnipam is considered advantageous because of the assumed lower toxicity of pnvcl.
