Abstract
Official abstract text for this publication.
Provided are a chloroprene rubber that is less adhesive to rolls and gives a vulcanized product superior in physical properties, a production method thereof, a chloroprene rubber composition and a vulcanized product thereof. A chloroprene rubber comprising a steroid skeleton-containing compound. The chloroprene rubber may contain a steroid skeleton-containing compound in an amount of 0.01 to 1 mass %. A vulcanized product is prepared by vulcanizing a composition containing the chloroprene rubber. The chloroprene rubber can be prepared, for example, by emulsion-polymerizing chloroprene alone or chloroprene and other monomers in combination in the presence of a rosin containing a steroid skeleton-containing compound.
First claim
Opening claim text (preview).
The invention claimed is: 1. A chloroprene rubber comprising a steroid skeleton-containing compound; wherein the chloroprene rubber comprises the steroid skeleton-containing compound in an amount of 0.05 to 0.832 mass %. 2. A method for producing a chloroprene rubber, comprising emulsion-polymerizing chloroprene alone or chloroprene and other monomers in the presence of a rosin containing a steroid skeleton-containing compound, wherein the chloroprene rubber comprises the steroid skeleton-containing compound in an amount of 0.05 to 0.832 mass %. 3. The method for producing a chloroprene rubber according to claim 2 , wherein the rosin contains a steroid skeleton-containing compound in an amount of 0.2 to 20 mass %. 4. A chloroprene rubber composition comprising the chloroprene rubber according to claim 1 . 5. A vulcanized product prepared by vulcanizing the chloroprene rubber composition according to claim 4 . 6. The method for producing a chloroprene rubber according to claim 3 , wherein the rosin contains a steroid skeleton-containing compound in an amount of 0.3 to 8.0 mass %.
