Latest Patents

Ichihara's latest patents focus on a polyetheresteramide that exhibits excellent heat resistance and permanent antistatic properties. This innovative material demonstrates superior compatibility with thermoplastic resins. The polyetheresteramide is composed of a polyamide oligomer with carboxylic chain ends, which has a number average molecular weight ranging from 200 to 5,000, and a bisphenol compound with oxyalkylene units, having a number average molecular weight between 300 and 3,000. The antistatic resin compositions derived from this material can contain between 3 to 40% by weight of the polyetheresteramide and 60 to 97% by weight of thermoplastic resins. Furthermore, these compositions can include compatibilizers such as vinyl polymers with functional groups or block polymers that combine polyolefin and aromatic vinyl polymer blocks. To enhance the antistatic properties, a composition with at least 97% by weight of the polyetheresteramide and a minimum of 0.01% by weight of an alkali metal or alkaline earth metal halide can also be utilized.
