It is desirable that the phenolic derivative is at least one member selected from 4,4'-thiodiphenol, 4,4'-dihydroxydiphenylmethane, and 4,4'-dihydroxydiphenyl ether. It is desirable that a film or sheet obtained from the composition has a modulus of elasticity of 10-500 MPa when measured according to the testing method JIS K6732. The lactate resin is exemplified by a polylactic acid or a copolymer of lactic acid with another aliphatic hydroxycarboxylic acid.

SOLUTION: A polysaccharide such as acetylcellulose having a weight-average molecular weight of 3,000-500,000 is dehydratively condensed with at least either lactic acid or a polylactic acid to obtain a degradable copolymer having a melt tension of 0.7-20 g at a melt flow index of 10 g/10 min. 100 pts.wt. obtained copolymer is mixed with 0.1-5 pts.wt. inorganic filler blowing nucleator such as talc having a mean particle diameter of 1-10 μm, 0.01-0.5 pt.wt. blowing aid such as calcium stearate, and 0.1-20 pts.wt. volatile blowing agent such as methyl chloride or carbon dioxide to obtain the objective composition. This composition is extruded at 150-250 deg.C with e.g. a tandem foaming extruder to obtain a foam having an expansion ratio of 5-30 and a cell diameter of 100-600 nm.

摘要： PROBLEM TO BE SOLVED: To prevent natural environmental disruption caused by leaving a ball marker as it is by including biodegradable resins in the ball marker. SOLUTION: For example, about 400 g of L-lactide, about 0.04 g of octanoic acid primary tin, and about 0.12 g of lauryl alcohol are sealed in a cylindrical stainless-steel polymerized container with an agitator. After vacuum-evaporating them, they are substituted nitrogen gas and are reacted by heating to produce a polylactatic acid melting substance. This substance is cut by a pelletizer to obtain polylactatic acid of molecular weight average of about 138 thousand. A ball marker for golf is formed from this polylactatic acid by injection molding. According to an examination of resolvability of the ball marker after using it on golf green and burying it in compost, the ball marker is excellent in practicality and resolvability and is resolved with no trace of the original form after at least one to six months. Environmental disruption can be prevented thereby.
