摘要

The invention relates to plastic compounds for preparing films in a masterbatch containing zeolite with surfaces modified by silylation reaction. The films can be obtained through thermoplastic processing by blending the masterbatch with polymers such as polyolefins and polystyrene. The masterbatch includes styrene-b-(ethylene-ran-butylene)-b-styrene copolymers with styrene to ethylene-ran-butylene content of 12:88 to 14:86, and zeolites surfaces modified by silylation reaction with organosilane compound, in 30% to 70% by weight of copolymer with zeolite. The organosilane formula is R1nSiR2R3-n, where R is methoxy, ethoxy or chloro group, R1 is methyl group, R2 is functional group capable of a forming - interaction from phenyl, phenylethyl, vinyl, or propyl methacrylate groups, and n is 0 and 2. The films provide higher ethylene transmission and selectivity than films of pure polymers with unmodified zeolite, and can be used for packaging to retard ripening of fresh produce, in particular, ethylene-sensitive commodities.
