Title:
METHOD FOR PRODUCING SYNTHETIC POLYISOPRENE LATEX
Document Type and Number:
WIPO Patent Application WO/2018/092603
Kind Code:
A1
Abstract:
This method for producing a synthetic polyisoprene latex is provided with a step for mixing a latex of a synthetic polyisoprene (A) synthesized using a Ziegler catalyst and a latex of a synthetic polyisoprene (B) synthesized using an organic alkali metal catalyst at a weight ratio in which "synthetic polyisoprene (A) : synthetic polyisoprene (B) = 10 : 90 to 90 : 10". In a method for producing a laminate according to the present invention, the weight-average molecular weight of the synthetic polyisoprene (A) is preferably 100,000 to 3,000,000 and the weight-average molecular weight of the synthetic polyisoprene (B) is preferably 1,000,000 to 5,000,000.
