Poly tetramethylene oxide ptmo
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. Polytetrahydrofuran, also called poly(tetramethylene ether) glycol or poly(tetramethylene oxide), is a chemical compound with formula (C 4H 8O)nOH2 or HO-(-(CH2)4O-)n-H. It can be viewed as a polymer of tetrahydrofuran, or as the polyether derived from 1,4-butanediol. The product is commercially available as polymers of low average molecular w…
