Soluble Polvarvlene ether ketones The present invention relates to polyarylene ether ketones which are soluble in halogenated hydrocarbons and contain 2,2'-bis(benzoyl)biphenyl units, to the preparation thereof, to the mouldings, coatings or sheets made therefrom, and to the use of said polyarylene ether ketones for modifying matrix resins.
Polyarylene ether ketones are industrial materials having very good mechanical and thermal properties which are normally insoluble in halogenated hydrocarbons or form unstable solutions. For example, polyarylene ether ketones containing 4,4'-bis(benzoyl)biphenyl units are disclosed in EP-A-0 194 062. These keto group containing polyethers have especially good resistance to solvents, for example to methylene chloride.
For many utilities, especially for modifying duromer matrix resins, polyether ketones are required which have enhanced solubility properties without any substantial reduction of the thermal properties, such as glass transition temperature. Surprisingly, it has now been found that polyarylene ether ketones containing 2,2'-bis(benzoyl)biphenyl units are readily soluble in customary organic solvents, preferably in halogenated hydrocarbons, and form stable solutions.
Accordingly, the invention relates to polyarylene ether ketones which are soluble in halogenated hydrocarbons and have a reduced viscosity of 0.1 to 2.0 dl/g, measured at 25C using a 1 % solution of the polymer in N-methylpyrrolidone (NMP), which polyarylene ether ketones contain, based on the total number of structural units present in the polyarylene ether ketone resin, 1-100 mol % of a recurring structural unit of formula I

As mentioned at the outset, the polyarylene ether ketones of this invention are soluble in customary organic solvents, preferably in halogenated, i,.e. chlorinated or fluorinated, hydrocarbons, especially in chlorinated hydrocarbons such as methylene chloride,trichloromethane, dichloroethane, trichloroethane or chlorobenzene. The novel poly-arylene ether sulfones are also soluble in polar aprotic solvents such as N-methyl-pyrrolidone, N,N-dimethylformamide, dimethyl sulfoxide and sulfolane, or usually also in cyclic ethers such as tetrahydrofuran or dioxane, as well as in cyclohexanone orcyclopentanone. On account of their solubility, the polyarylene ether ketones may with advantage be processed to films or incorporated in other matrix systems.
The solutions of the polymers of this invention are stable over several weeks, i.e. no turbidity or precipitation of the polymer occurs. The invention therefore further relates to a solution containing 1 to 75 % by weight, preferably 5 to 50 %, by weight, based on said solution, of a polyarylene ether ketone of this invention.
The polyarylene ether ketones can be used in the conventional manner for thermoplastics and processed to mouldings, films, sheets or coatings. The invention thus also relates to the objects made from the polyarylene ether resins, such as mouldings, coatings, films or sheets.
Prior to processing, for example as melt or, more particularly, as solution, the polyarylene ether ketones may be blended with customary modifiers such as fillers, pigments,stabilisers or reinforcing agents such as carbon, boron, metal or glass fibres.
The polyarylene ether ketones may also be used as matrix resins for the fabrication of f1brous composite systems, for which utility it is possible to use as reinforcing fibres the fibres conventionally used for reinforcing industrial materials. These fibres may be organic or inorganic fibres, natural fibres or synthetic fibres, and may be in the form of fibre bundles as oriented or non-oriented fibres or continuous filaments.
A further preferred utility of the polyarylene ether ketones of this invention is, by virtue of their solubility, the modification of other matrix resins. Thus, for example, preferably concentrated solutions of these polymers in customary organic solvents will ordinarily be used for modifying duromer matrix resins with thermoplastics. It must be possible to 2~39478 remove the solvents rapidly after incorporation and they should therefore have as low boiling points and high volatility points as possible.
The invention further relatcs to the use of the novel polyarylene ether ketones for modifying thermoplastic and du}omer matrix resins~

These keto group containing polyethers have especially good resistance to solvents, for example to methylene chloride.

Surprisingly, it has now been found that polyarylene ether ketones containing 2,2'-bis(benzoyl)biphenyl units are readily soluble in customary organic solvents, preferably in halogenated hydrocarbons, and form stable solutions.

As mentioned at the outset, the polyarylene ether ketones of this invention are soluble in customary organic solvents, preferably in halogenated, i,.e. chlorinated or fluorinated, hydrocarbons, especially in chlorinated hydrocarbons such as methylene chloride,trichloromethane, dichloroethane, trichloroethane or chlorobenzene. The novel poly-arylene ether sulfones are also soluble in polar aprotic solvents such as N-methyl-pyrrolidone, N,N-dimethylformamide, dimethyl sulfoxide and sulfolane, or usually also in cyclic ethers such as tetrahydrofuran or dioxane, as well as in cyclohexanone orcyclopentanone. On account of their solubility, the polyarylene ether ketones may with advantage be processed to films or incorporated in other matrix systems.
The solutions of the polymers of this invention are stable over several weeks, i.e. no turbidity or precipitation of the polymer occurs. The invention therefore further relates to a solution containing 1 to 75 % by weight, preferably 5 to 50 %, by weight, based on said solution, of a polyarylene ether ketone of this invention.
The polyarylene ether ketones can be used in the conventional manner for thermoplastics and processed to mouldings, films, sheets or coatings. The invention thus also relates to the objects made from the polyarylene ether resins, such as mouldings, coatings, films or sheets.
Prior to processing, for example as melt or, more particularly, as solution, the polyarylene ether ketones may be blended with customary modifiers such as fillers, pigments,stabilisers or reinforcing agents such as carbon, boron, metal or glass fibres.
The polyarylene ether ketones may also be used as matrix resins for the fabrication of f1brous composite systems, for which utility it is possible to use as reinforcing fibres the fibres conventionally used for reinforcing industrial materials. These fibres may be organic or inorganic fibres, natural fibres or synthetic fibres, and may be in the form of fibre bundles as oriented or non-oriented fibres or continuous filaments.
A further preferred utility of the polyarylene ether ketones of this invention is, by virtue of their solubility, the modification of other matrix resins. Thus, for example, preferably concentrated solutions of these polymers in customary organic solvents will ordinarily be used for modifying duromer matrix resins with thermoplastics. It must be possible to 2~39478 remove the solvents rapidly after incorporation and they should therefore have as low boiling points and high volatility points as possible.
The invention further relatcs to the use of the novel polyarylene ether ketones for modifying thermoplastic and du}omer matrix resins~
