ABSTRACT:
An additive for synthetic resins is provided. The additive comprises particles surface-coated with a petaloid porous hydroxyapatite having a chemical formula Ca.sub.5 (PO.sub.4).sub.3 (OH) and the petaloid porous hydroxyapatite is not less than 5% by weight of the particles. The additive can be added to any kinds of synthetic resins. If the additive is used in a polyethylene film, blocking of the film is not only prevented, but good transparency and good anti-scratch ability are imparted, and if the additive is used in a polyester, a film having good slipperiness, anti-abrasion and less coarse protrusions can be provided.
