Titanate ester cure of unsaturated elastomers

摘要

Unsaturated elastomers (e.g., cis-polyisoprene) and blends containing unsaturated elastomers can be cured (gelled) by admixing with 1 to 10 phr organo titanate ester [(RO)4Ti, e.g., tetra-n-butyl titanate]. Gellation takes place only when the mixture is exposed to the open atmosphere and can be prevented by maintaining the mixture in a closed system.
