Process for elastomer viscosity stabilization |
| abstract |
The viscosity of chloroprene polymers is stabilized by addition to the polymer of 0.1-5 weight % of an ester, amide, or amic acid derived from maleic acid or fumaric acid or a diacylethylene compound or from their halogenated derivatives. Stabilization of chloroprene polymers made in the absence of elemental sulfur allows them to be mixed under high temperature/high shear conditions, without undergoing substantial crosslinking for practical periods. Sulfur-modified chloroprene polymers are stabilized against viscosity increases during ambient temperature aging. Blends of either type of chloroprene polymers with hydrocarbon diene elastomers can be similarly stabilized. |
