RESIN COMPOSITION AND AGRICULTURAL FILM

摘要

A resin composition which exhibits an excellent heat-retaining property without reducing transparency when it is used as an agricultural film. The resin composition comprises 100 parts by weight of a resin and 1 to 20 parts by weight of a heat-retaining agent which is represented by the following formula (1) and has a difference between the molar ratio obtained from 2¸ of the (110) plane by an X-ray diffraction method and the molar ratio obtained by chemical analysis of not more than 0.7 7 (the molar ratio is an Mg/Al 2 value).
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒMg X Al 2 (OH) 2X+4 (CO 3 )·mH 2 O€ƒ€ƒ€ƒ€ƒ€ƒ(1)
(In the above formula, X satisfies 4.0 < X ‰¦ 6.5, and "m" is 0 or a positive number.)
