Title:
METHOD FOR PRODUCING ELASTOMER PELLETS
Document Type and Number:
WIPO Patent Application WO/2024/070594
Kind Code:
A1
Abstract:
Provided is a method for producing elastomer pellets, the method comprising a step for hot-cutting an elastomer, in which the step for hot-cutting the elastomer includes cooling the elastomer extruded through the die hole with cooling water, and the value of a parameter A represented by general formula (I) is 1.8 or less. (I): A=-X0.41-Y0.36+Z0.71 (In general formula (I), X represents the weight average molecular weight (unit: ten-thousand) of the elastomer; Y represents the shear rate [1/sec] of the elastomer in the die hole; and Z represents the temperature [°C] of the cooling water for the elastomer.)
