Product Name: n-vinylcaprolactam
CAS Number: 2235 - 00 - 9
Appearance: It is usually a colorless to pale - yellow liquid or solid depending on the temperature. The melting point is around 38 - 40 °C, and the boiling point is approximately 122 - 125 °C at 2 mmHg. The density of n - vinylcaprolactam is about 1.04 g/cm³.
Purity: Our factory supplies high - purity n - vinylcaprolactam, with a purity level typically above 99%. This high purity ensures the effectiveness and stability of subsequent reactions and applications.
Polymer Synthesis: n - vinylcaprolactam is an important monomer for the synthesis of various polymers. Copolymers can be formed by reacting it with other monomers such as acrylic acid, acrylamide, etc. These copolymers have excellent solubility, film - forming properties, and adhesion, and are widely used in the fields of coatings, adhesives, and printing inks.
Produtos de higiene pessoal: It can be used in the formulation of hairspray, mousse, and other hair - styling products. The polymers formed from n - vinylcaprolactam can provide good hold and flexibility to the hair, making the hair look natural and shiny.
Domínio biomédico: Due to its good biocompatibility, n - vinylcaprolactam - based polymers can be used as drug carriers in drug delivery systems. They can control the release rate of drugs, improve the bioavailability of drugs, and reduce side effects.
Armazenamento: n - vinylcaprolactam should be stored in a cool, dry, and well - ventilated place. Keep it away from direct sunlight, heat sources, and oxidizing agents. It is recommended to store it in a tightly sealed container to prevent moisture and air from entering.
Manuseamento: When handling n - vinylcaprolactam, appropriate personal protective equipment should be worn, including gloves, safety glasses, and a lab coat. In case of contact with skin or eyes, immediately rinse with plenty of water and seek medical attention if necessary.
Condições de reação: In polymer synthesis, the reaction temperature, time, and initiator concentration need to be carefully controlled. For example, when using a free - radical initiator, the reaction temperature is usually between 60 - 80 °C, and the reaction time can range from several hours to tens of hours depending on the specific reaction system.
Case 1: Coating Application
A coating manufacturer wanted to develop a high - performance water - based coating. They used n - vinylcaprolactam to copolymerize with acrylic monomers. The resulting copolymer had excellent adhesion to various substrates, such as metal and plastic. The coating showed good abrasion resistance and chemical resistance. In a practical test, the coated metal parts were exposed to a corrosive environment for 3 months, and there was only minor surface damage, demonstrating the effectiveness of n - vinylcaprolactam in improving coating performance.
Case 2: Hair - Styling Product
A cosmetic company introduced a new hairspray containing n - vinylcaprolactam - based polymers. In consumer trials, over 80% of the participants reported that the hairspray provided long - lasting hold without making the hair feel stiff. The hair looked natural and had a healthy shine. The product quickly gained popularity in the market due to its superior performance.
Case 3: Drug Delivery System
A research team in the biomedical field designed a drug delivery system using n - vinylcaprolactam - based polymers. They loaded an anti - cancer drug into the polymer matrix. In in - vitro tests, the drug was released in a controlled manner over a period of several days. This controlled - release system has the potential to improve the treatment effect of cancer by maintaining a steady drug concentration in the body.
