Polymer of 2-methyloxirane and oxirane
CAS 9003-11-6
What Is Polymer of 2-methyloxirane and oxirane?
This synthetic polymer is used in industrial applications and some specialty coatings. While not typically found in consumer products, it may appear in certain adhesives or surface treatments. Its unique properties make it valuable for creating flexible, durable materials that resist degradation.
Safety Profile
PROFESSIONAL USEWhat Does Polymer of 2-methyloxirane and oxirane Smell Like?
This polymer is generally odorless in its pure form. Its high molecular weight and synthetic nature make it non-volatile, so it does not contribute to fragrance profiles. Industrial grades may have trace impurities that introduce faint chemical or plastic-like odors, but these are not characteristic of the pure material.

Chemistry, Properties & Perfumer Guide
The Chemistry
A copolymer of propylene oxide (2-methyloxirane) and ethylene oxide (oxirane) with variable monomer ratios. Produced via anionic polymerization using catalysts like potassium hydroxide. Chain length and branching are controlled during synthesis to achieve desired physical properties. The ether linkages provide flexibility while the methyl groups influence hydrophobicity.
