Title:

合成ポリイソプレンラテックスの製造方法

Document Type and Number:

Japanese Patent JP6984609

Kind Code:

B2

Abstract:

Provided is a method for producing a synthetic polyisoprene latex, including a step of mixing a latex of synthetic polyisoprene (A) synthesized by use of a Ziegler type catalyst and a latex of synthetic polyisoprene (B) synthesized by use of an organic alkali metal catalyst at a weight ratio of "synthetic polyisoprene (A) : synthetic polyisoprene (B) = 10:90 to 90:10". In the method for producing a synthetic polyisoprene latex of the present invention, preferably, the weight average molecular weight of the synthetic polyisoprene (A) is 100,000 to 3,000,000 and the weight average molecular weight of the synthetic polyisoprene (B) is 1,000,000 to 5,000,000.
