Abstract: An encapsulated particle comprises a core particle, a transferrable-pesticide disposed about the core particle, and a polyurethane layer disposed about the transferrable-pesticide. The core particle comprises a fertilizer, such as urea. The transferrable-pesticide can comprise a dinitroaniline, such as pendimethalin. The polyurethane layer is generally formed from a reaction mixture having a maximum temperature of no greater than about 30 ?C. The polyurethane layer inhibits the transferrable-pesticide from transferring to a surface different from the core particle when the encapsulated particle physically contacts the surface. A method of forming the encapsulated particle comprises the steps of encapsulating the core particle with the transferrable-pesticide to form an intermediate-particle, combining an isocyanate and a polyol to form the reaction mixture, and encapsulating the intermediate- particle with the reaction mixture to form the polyurethane layer of the encapsulated particle. The polyurethane layer comprises the reaction product of the isocyanate and polyol.

Abstract: Una combinación única de un poliol hidrofílico (A) y un poliol hidrofóbico (B) que tienen una protección de óxido de etileno terminal se utilizan en una composición de resma y un sistema de poliuretano, y se utilizan para formar un artículo de poliuretano, tal como una espuma de poliuretano. El poliol hidrofílico (A) es rico en óxido de etileno (EO) y el poliol hidrofóbico (B) es rico en óxido de propileno (PO). El poliol hidrofílico (A) y el poliol hidrofóbico (B) se presentan en la composición de resma y el sistema de poliuretano en una relación en peso (A:B) de 1.5:1 a 20:1. El artículo de poliuretano exhibe excelente confort para el uso en aplicaciones vehiculares, tal como un asiento para automóviles y motocicletas, debido a la frecuencia de resonancia reducida y la transmisividad de vibración máxima con relación a los artículos de poliuretano previos.

Abstract: A unique combination ofa hydrophilic polyol (A) and a hydrophobic polyol (B) having a terminal ethylene oxide cap are used in a resin composition and a polyurethane system, and are used to form a polyurethane article, such as a polyurethane foam. The hydrophilic polyol (A) is ethylene oxide (EO) rich and the hydrophobic polyol (B) is propylene oxide (PO) rich. The hydrophili c polyol (A) and the hydrophobic polyol (B) are present in the resin composi tion and the polyurethane system in a weight ratio (A:B) of from 1.5:1 to 20 :1. The polyurethane article exhibits excellent comfort for use in vehicle a pplications, such as automotive and motorcycle seating, due to reduced reson ance frequency and reduced peak vibration transmissivity relative to previou s polyurethane articles.
