红外光谱研究表明，PMMA与PVC共混物的相容性是由于PMMA中的C=O与PVC中CHCl中的氢形成氢键所致。该混合体系在整个组成范围内均掺杂樟脑磺酸（CSA）。CSA在PVC、PMMA和PMMA-PVC共混物中的掺杂使FTIR光谱发生变化。PVC与CSA之间的相互作用是通过CSA的C=O与PVC的CHCl之间的氢键作用实现的。CSA掺杂PMMA，表明CSA中的H +离子与PMMA中的C=O和-OCH 3中的氧原子发生了相互作用。而在PMMA-PVC共混体系中，CSA中的H +离子与PMMA中C=O中的氧原子相互作用。
The IR spectroscopy study shows miscibility between PMMA-PVC blends due to hydrogen bonding between C=O of PMMA and hydrogen from CHCl of PVC. This blend system is doped by Camphor Sulphonic Acid (CSA) in the entire composition range. The doping of CSA in PVC, in PMMA and in PMMA-PVC blends shows changes in FTIR spectra. The interaction between PVC and CSA is through hydrogen bonding between C=O of CSA and CHCl of PVC. Doping PMMA with CSA, indicate an interaction between H + ion of CSA and oxygen atoms of C=O and -OCH 3 of PMMA. Whereas in PMMA-PVC blend interaction between H + ion of CSA and oxygen atom of C=O of PMMA.
