Abstract
Essentially ETU-free cross linkable compositions comprising chloroprene rubber, a cross-linker and a vulcanization accelerator, which have a defined content of ions from the second or third main group and resinate anions and thus possesses improved curing characteristics, a process for vulcanization of such compositions and vulcanizates obtained thereby.
Claims16
A cross-linkable composition comprising:
- a chloroprene rubber comprising:
- cations of metals from the second or third main group in an amount of more than 0.25% by weight based on the total amount of chloroprene rubber;
- resinate anions in an amount of more than 2.5% by weight and less than 4.5% by weight based on the total amount of chloroprene rubber;
- a cross-linker, and
- a vulcanization accelerator selected from N-methyl-thiazolidine-2-thione derivatives.
A chloroprene rubber comprising cations of metals from the second or third main group, in an amount of more than 2.5% by weight and less than 4.5% by weight based on the total amount of chloroprene rubber.
