The kinetics of three dimensional polymerization and the properties of crosslinked polyether urethane elastomers synthesized with the participation of 2,2-bis-(4-isocyanatophenyl) hexafluoropropane

Add time:07/23/2019    Source:sciencedirect.com

A kinetic study has been made of the three dimensional polymerization of a system including copolymer of tetrahydrofuran and propylene oxide, 1,1,1-trimethylolpropane and 2,2-bis-(4-isocyanatophenyl)hexafluoropropane in the temperature interval 27–80°. The effect of polymerization temperature in the kinetics of the gelatin process has been investigated as well as physico-chemical and mechanical properties of the crosslinked polyether urethanes.
