Description

Poly(Vinyl Cinnamate) is a specialized photosensitive polymer derived from the esterification of poly(vinyl alcohol) with cinnamic acid. This compound is valued for its unique ability to undergo cross-linking upon exposure to ultraviolet (UV) light, a property critical for creating precise, insoluble patterns. It serves as a key photoresist material in the microfabrication of electronic components and advanced optical devices. Industries involved in semiconductor manufacturing, photolithography, and high-resolution printing rely on its consistent performance for patterning and imaging applications.

Application

• Primary component in negative-tone photoresists for semiconductor and microelectronics fabrication.
• Photosensitive material for high-resolution optical lithography and waveguide patterning.
• Key ingredient in UV-curable coatings and inks for specialized printing applications.
• Used in research and development of holographic recording media and data storage systems.
• Cross-linking agent in the production of specialty polymers with tailored light-responsive properties.
• Material for creating micro-optical elements and diffraction gratings.

Quality Control

Our Poly(Vinyl Cinnamate) is manufactured under controlled conditions to ensure batch-to-batch consistency and performance reliability for photolithographic applications. Quality is verified through a suite of analytical tests including determination of degree of substitution, molecular weight distribution, and photosensitivity. A Certificate of Analysis (COA) detailing specific results for purity, viscosity, and UV response is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and should be handled under yellow or red safelight conditions in relevant application environments to prevent premature cross-linking. Keep the container tightly sealed to minimize exposure to moisture.
