Phosphorus-based flame retardant systems are used in these fire-safe polymers and are based on aluminium diethyl phosphinate and synergists. The geometrical isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule. Keywords Polybutene-1 PBT can also be made into yarn. The pre-catalysts are activated by combinations of organoaluminum compounds and other types of organic or organometallic modifiers. PBT resists solvents, shrinks very little during forming, is mechanically strong, is heat-resistant up to 150 C (or 200 C with glass-fibre reinforcement), and can be treated with flame retardants to make it noncombustible. The lower molecular weight of polybutene is one reason why polybutenes are liquids. Their low polarity, low degree of unsaturation, and their closely packed, branched-chain molecular structure make Polybutenes resistant to chemical reaction. COPYRIGHT TER Chemicals GmbH & Co.
