Web1.1 Poly(tetramethylene oxide) Poly(tetramethylene oxide) (PTMO) is a soft, flexible polymer with a glass transition temperature of -86oC and a melting temperature of … WebHigher PDMS levels did reduce tensile strength, probably because of the reduction in strain crystallizing II PTMO content. The PDMS modification, which resulted in improved fire resistance and excellent mechanical properties, is attributed to the low surface energy of the PDMS segment that tended to migrate to the surface of the polymer.
