Abstract: Impact-cushioning particles contain a poly(3-hydroxybutyrate) resin component. The poly(3-hydroxybutyrate) resin component contains a copolymer component (A), and the copolymer component (A) includes a copolymer (A-1) and/or a copolymer (A-2). The impact-cushioning particles are suitable for use in artificial turf or a paved structure. Copolymer (A-1) is a copolymer of 3-hydroxybutyrate units and other hydroxyalkanoate units, in which the content of the other hydroxyalkanoate units is from 1 to less than 10 mol %. Copolymer (A-2) is a copolymer of 3-hydroxybutyrate units and other hydroxyalkanoate units, in which the content of the other hydroxyalkanoate units is 24 mol % or more.
