Description
Poly(arylene ether) composition Cross-reference of related applications This application claims the priority and benefit of European patent application no. 19189450.0 filed with the European Patent Office on July 31, 2019, the entire contents of which are incorporated herein by reference. Poly(arylene ether) copolymers are a class of thermoplastic resins known for their excellent water resistance, dimensional stability, and inherent flame retardancy, as well as their superior dielectric properties over a wide frequency and temperature range. Properties such as ductility, stiffness, chemical resistance, and heat resistance allow thermosetting poly(arylene ether) copolymers to be reacted with various crosslinking agents to meet the requirements of various end applications, such as fluid engineering components, electrical enclosures, automotive parts, and insulation for wires and cables. In particular, poly(arylene ether) copolymers have been used in thermosetting compositions for electronic applications, providing improved toughness and dielectric properties among other advantages. Phenols, such as uncapped poly(phenylene ether) (PPE), are used as blocking agents for polyurethanes, particularly for coating and adhesive applications. PPE blocking agents can minimize moisture sensitivity in the system, thereby reducing free isocyanates in polyurethane systems and extending storage stability. The phenolic terminal groups of PPE blocking agents form reversible bonds with isocyanates, where deblocking occurs at high temperatures. However, the reversible nature of these bonds limits the use of phenolic PPE in final polyurethane products due to a lack of thermal stability. It would be advantageous to use capped PPE copolymers in final polyurethane products to impart improved properties, including low moisture absorption, an increased glass transition temperature ( Tg ), improved tear strength, chemical resistance, and flame retardancy. Polyurethanes are generally prepared by reacting a polyol with a (poly)isocyanate in the presence of a catalyst. For stability during preparation, the (poly)isocyanate may be blocked by a blocking agent, wherein at least one isocyanate group reacts with the protective agent or blocking agent to form a derivative (also referred to as "blocked poly(isocyanate)"), and this derivative can be dissociated upon heating to remove the protective agent or blocking agent (also referred to as de-blocking) and release a reactive isocyanate group. The reactive isocyanate group can subsequently react with the polyol to achieve the polymerization of the polyurethane. However, due to the nature of the blocking chemical, both heating and a longer reaction time may be required to proceed. In sheet applications, polyurethane coatings can be applied to flat or gently curved end parts manufactured by injection molding or thermoforming via flow or dip coating, performed under conditions that minimize deblocking before curing, and subsequently cured by heat or irradiation. In the case of thermoplastic polyurethanes, the thermopolymer can be shaped and then post-coated and cured to produce a final product for a given application. These techniques have the disadvantage of being time-intensive because the blocking chemical reactions of (poly)isocyanates are inherently slow. For processes such as dip coating, there is additional time required to apply the coating to the substrate before curing even begins. Phenolic compounds, such as uncapped poly(phenylene ether) (PPE) copolymers, can be used as blocking agents in polyurethanes to reduce free isocyanate groups and provide extended storage stability. Additionally, uncapped PPE copolymers can react with isocyanate groups under specific conditions to allow the uncapped PPE copolymer to be incorporated into the structure of the final polyurethane product. The phenolic terminal groups of uncapped PPE copolymers can form reversible bonds with the isocyanate groups of (poly)isocyanates, which makes uncapped PPE copolymers useful as blocking agents. However, the reversible nature of these bonds can also limit the use of uncapped PPE copolymers in polyurethane compositions because they react with isocyanate groups as polyols during polymer formation, and also limit the thermal stability of the bond formed between the phenolic hydroxyl group and the isocyanate group, so the thermal stability of the final polyurethane product is similarly limited, especially at high temperatures. In overcoming the limitations of uncapped PPE copolymers in this type of polyurethane composition, the inventors have discovered that a capped poly(arylene ether) copolymer containing an aliphatic hydroxyl terminal cap (also called a terminal group) can be used instead of an uncapped PPE copolymer. The aliphatic alcohol group of the capped poly(arylene ether) copolymer reacts favorably to form a thermally strong bond with the isocyanate group of the (poly)isocyanate, and the resulting polyurethan
