Abstract
Official abstract text for this publication.
A dip-molded article includes an external molded layer and internal molded layer. The external molded layer includes a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 35 wt % to 60 wt %, and the internal molded layer in which a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 10 wt % to 28 wt %.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dip-molded article comprising: an external molded layer in which a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 35 wt % to 60 wt %; and an internal molded layer in which a content of an ethylenically unsaturated nitrile-based monomer-derived repeating unit is 10 wt % to 28 wt %. 2. The dip-molded article of claim 1 , wherein each of the external molded layer and the internal molded layer further includes a conjugated diene-based monomer-derived repeating unit and an ethylenically unsaturated acid monomer-derived repeating unit. 3. The dip-molded article of claim 2 , wherein a content of the conjugated diene-based monomer-derived repeating unit included in the external molded layer is 30 wt % to 65 wt %, and a content of the ethylenically unsaturated acid monomer-derived repeating unit included in the external molded layer is 0.1 wt % to 10 wt %. 4. The dip-molded article of claim 2 , wherein a content of the conjugated diene-based monomer-derived repeating unit included in the internal molded layer is 60 wt % to 90 wt %, and a content of the ethylenically unsaturated acid monomer-derived repeating unit included in the internal molded layer is 0.1 wt % to 10 wt %. 5. The dip-molded article of claim 1 , wherein a ratio of a thickness of the external molded layer and a thickness of the internal molded layer is 1:9 to 9:1. 6. The dip-molded article of claim 1 , wherein a ratio of a thickness of the external molded layer and a thickness of the internal molded layer is 1.5:1 to 2.5:1.
