▎ 摘  要

NOVELTY - Golf ball comprises a core formed from a mixture comprising 1,4 polybutadiene with a cis content of more than 50% and containing a metal salt of acrylate, where 1,4 polybutadiene has 5-60 wt.% metal salt of acrylate chemically attached to a main chain of 1, 4 polybutadiene, 0.4-2.5 wt.% graphene material, 1-30 wt.% polyisoprene, 10-50 wt.% zinc diacrylate, 1-30 wt.% zinc oxide, 1-20 wt.% zinc stearate, and 0.1-10 wt.% peroxide initiator; an inner mantle arranged over the core; an outer mantle arranged over the inner mantle; and a cover layer over the outer mantle. USE - As golf ball. ADVANTAGE - The golf ball has desired ball performance, increased consistency of physical properties, increased coefficient of restitution using mixture of metal cations and reduced manufacturing cost by reducing kneading time.
