  • Resin additive composition and process for producing the same
    Patent number: 7052630
    Abstract: In this application is disclosed a resin additive composition which can by produced by precipitating a calix(n+m+l)arene represented by the following general formula (2) and in a dissolved state together with or at the same time at least one functional ingredient selected from the group consisting of various water-soluble or hydrophilic resin flam-retardants, resin thermal stabilizers and resin curing agents, and in a dissolved or suspended state. This resin additive composition has a good affinity for organic polymers such as polyolefin and the like, which allows the functional ingredient(s) to be dispersed homogeneously in the resin. Therefore are provided high-performance resin compositions comprising various functional ingredient(s).
