摘要： Solid organic phosphites in powder form, used to endow organic polymers with stability characteristics are made resistant to hydrolysis by treating said powder phosphites with a silane containing in its molecule at least two alkoxy groups and causing the silane to hydrolyze, and the formation and deposition of a siliconic polymer on the surface of powder particles to occur.

摘要： Granular form of a mixture comprising: (a) a nickel-quencher corresponding to [2,2′-thio-bis(4-t-octyl-phenolate)-n-butylamine Nickel (II)]; (b) a 2-hydroxy-4-alkyloxybenzophenone corresponding to 2-hydroxy-4-n-octyloxybenzophenone; characterized in that it has two diffraction lines at angles 2&thgr;=17.593 and 2&thgr;=22.023 in the X-Ray diffraction spectrum from powders. The above granular form can be used as a light stabilizer for agricultural films based on polyolefins or olefinic copolymers.

摘要： Tetrakis[3,5-di-tert.butyl-4-hydroxyphenyl)-propionyl-oxymethyl]methane with amorphous structure, with glass transition temperature T.sub.g comprised within the range of from about 40.degree. C. to 50.degree. C. and free from endothermic melting peaks at temperatures higher than 50.degree. C. and of up to 200.degree. C. is obtained by means of the melting of crystalline tetrakis[3-(3,5-di-tert.butyl-4-hydroxyphenul)-propionyl-oxymethyl]methane and sudden cooling of the molten material.
