Title:
BALE MOLDING OF CONJUGATED DIENE POLYMER
Document Type and Number:
Japanese Patent JP2018145360
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bale molding of a conjugated diene polymer that prevents a conjugated diene polymer particle from peeling from its surface and has a reduced expansion rate.SOLUTION: A bale molding of a conjugated diene polymer contains: 100 pts.mass of a conjugated diene, preferably 1,3-butadiene, isoprene polymer; and 3-60 pts.mass of an additive, having an SP value of 7-9.5 [(cal/ml)], preferably comprising petroleum resin, coumarone indene resin, terpene resin, or rosin resin. In the molding, the additive has a softening point of -40 to 100°C, preferably. In the molding, the conjugated diene copolymer contains 30-90 mass% of a conjugated diene polymer having 1,000,000 or more molecular weight.SELECTED DRAWING: Figure 3
