How can you identify PVC from FTIR?
This page summarizes the recurring FTIR evidence reported for PVC, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Respuesta rápida
PVC is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Interpretación de picos
Materiales / grupos posibles
| Grupo funcional | Evidencia |
|---|---|
| Alkyl C-H | 49 |
| Chlorine | 20 |
| Methoxy (OCH3) | 16 |
| Methacrylate | 15 |
| Acetate | 15 |
| C-O single bond | 14 |
| Carbonyl (C=O) | 7 |
| Hydroxyl (O-H) | 7 |
Lógica de espectro
The logic here is evidence aggregation: repeated literature mentions of PVC, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.
Uso en el mundo real
Esta página está diseñada para la identificación de polímeros, control de calidad de materiales entrantes, análisis de plásticos desconocidos, revisión de contenido reciclado e interpretación respaldada por la literatura de espectros de referencia.
Errores comunes
- Llamar a una coincidencia de material demasiado pronto porque está presente un pico famoso.
- Ignorando la preparación de la muestra, cargas, oxidación, agua o aditivos que pueden cambiar el patrón aparente.
- Usando evidencia de la literatura sin verificar si su propio modo de muestreo y calidad del espectro son comparables.
Consejo de verificación
Use DSC, GC-MS o TGA para validar la hipótesis del material cuando el patrón de picos sea ambiguo o mixto.
