Abstract
A latex composition contains a carboxy-modified conjugated diene polymer latex, a xanthogen compound, and a metal oxide.
Claims8
A latex composition comprising:
- a carboxy-modified synthetic polyisoprene latex;
- a zinc diisopropyl xanthate;
- and
- a metal oxide, wherein
- a carboxy-modified synthetic polyisoprene constituting the carboxy-modified synthetic polyisoprene latex is a polymer obtained by modifying a synthetic polyisoprene with a monomer having a carboxyl group selected from the group consisting of acrylic acid and methacrylic acid, and a content of isoprene unit in the synthetic polyisoprene is 95 wt % or more with respect to the total monomer unit,
- a content of the zinc diisopropyl xanthate is 0.01 to 10 parts by weight, with respect to 100 parts by weight of the carboxy-modified synthetic polyisoprene contained in the carboxy-modified synthetic polyisoprene latex, and
- the latex composition is free from dithiocarbamate vulcanization accelerators and thiazole vulcanization accelerators.
