Abstract
A process for producing an elastomeric article having an interpenetrating network structure included the following steps. Firstly, a mold is contacted with an elastomeric composition. The elastomeric composition includes a base latex and a thermoplastic ethylene-vinylacetate (EVA) copolymer latex. The base latex includes a styrene-butadiene rubber (SBR) latex and a carboxylated styrene-butadiene rubber (C-SBR) latex, and the mixing ratio of the base latex to the EVA copolymer latex is from 95:5 to 40:60. Then, the elastomeric composition on the mold is allowed to perform a vulcanization reaction, thereby forming the elastomeric article having the interpenetrating network structure.

A process for producing a glove having an interpenetrating network structure, comprising steps of:
- contacting a mold with an elastomeric composition comprising a base latex and a thermoplastic ethylene-vinylacetate (EVA) copolymer latex, said base latex comprising a styrene-butadiene rubber (SBR) latex and a carboxylated styrene-butadiene rubber (C-SBR) latex and the mixing ratio of said base latex to said EVA copolymer latex being from 95:5 to 40:60;
- and
- allowing said elastomeric composition on said mold to perform a vulcanization reaction, thereby forming said elastomeric article having said interpenetrating network structure.
A process for producing a glove having an interpenetrating network structure, comprising steps of:
- contacting a mold with an elastomeric composition, wherein said elastomeric composition comprises:
- 100 weight parts of a latex mixture comprising a base latex and a thermoplastic ethylene-vinylacetate (EVA) copolymer latex, said base latex comprising a styrene-butadiene rubber (SBR) latex and a carboxylated styrene-butadiene rubber (C-SBR) latex and the mixing ratio of said base latex to said EVA copolymer latex being from 99:1 to 5:95;
- 1˜10 weight parts of an activator, based on the total weight of said latex mixture;
- 0.1˜2 weight parts of a vulcanization agent, based on the total weight of said latex mixture;
- and
- 0.5˜10 weight parts of a vulcanization accelerator, based on the total weight of said latex mixture;
- and
- allowing said elastomeric composition on said mold to perform a vulcanization reaction, thereby forming said glove having said interpenetrating network structure.
