Description

  The present invention relates to a resin composition comprising a novel pseudo-crosslinked polymer and a polymer mixture thereof.

  In recent years, research and development on synthetic resins have progressed, and synthetic resins having various performances have been obtained. Among such research and development, many attempts have been made to impart new performance to an existing synthetic resin without impairing the inherent performance of the resin.

  Taking typical synthetic polymer materials as an example, acrylic resins or styrene resins are relatively inexpensive, have excellent transparency, and compare polymers with various characteristics from rubbery materials to glassy polymers. However, on the other hand, there remains a big problem in improving both strength, heat resistance and toughness. Lack of toughness is a problem common to all acrylic resins, and several methods for solving this have been reported. For example, it is known to add rubber particles to the resin (Japanese Patent Publication No. 58-167605, Japanese Patent Laid-Open No. 3-52910). However, these methods cannot solve the whitening phenomenon (bending processability) that occurs when the resin is bent. At present, no acrylic resin has been found that has both a glass transition point above room temperature and the ability to form a thin film (bending workability) that requires toughness.

  As the aromatic polyamide resin, polyparaphenylene terephthalamide can be given as the most typical resin. This has particularly excellent crystallinity, a high melting point and excellent flame retardancy, and has a high mechanical strength, a low linear expansion coefficient, etc. because of its rigid molecular structure. However, the problem of this resin is that it is hardly soluble in an organic solvent, and an inorganic strong acid such as concentrated sulfuric acid must be used as a solvent. Fibers spun from concentrated solutions such as concentrated sulfuric acid are known to exhibit high strength and elastic modulus, and have been industrially implemented. However, there are few application examples to a film, and it has only been reported that it can be achieved by stretching in a swollen state (JP-A-4-6738). In this method, the manufacturing process is very complicated, productivity is lowered, and further, the product price is increased. As a method for improving the solubility in an organic solvent, there is a method for improving the solubility in an organic solvent by copolymerizing a monomer having a halogen group introduced into an aromatic nucleus or a highly flexible monomer. Known (Japanese Patent Publication No. 56-45421). However, in this method, since the monomer is expensive, there is a concern that the product price is increased, the heat resistance and the flame retardance are impaired, and the metal corrosivity of halogen atoms becomes a problem.

  Since the liquid crystalline polymer exhibits a liquid crystal state in a molten state, it has a high elastic modulus and strength in the alignment direction, and further has a low linear expansion coefficient. However, the problems common to liquid crystal polymers are that the above performance in the direction perpendicular to the alignment direction is remarkably low, and the strength of the joined portion of the molten resin called weld that occurs when a molded product is obtained by injection molding is remarkably low. In addition, there may be mentioned a defect that the surface of the molded product is peeled off in layers. However, there is currently no known method for solving this problem.

  Polymer alloy materials are intended to develop new performance by mixing different types of polymer materials, but polymers with different affinity have been mixed by using compatibilizers. It was. This method is a technique aimed at reducing the surface energy with a compatibilizing agent, so that the dispersion state forming the sea-island structure can be controlled, but it cannot be completely compatibilized. There are no reports of complete compatibilization of dissimilar polymers. In addition, since compatibilizers are relatively expensive, if the product price is high and the polymer alloy material is used for a long period of time, the compatibilizer may bleed out to the surface, causing contamination. There is a problem that the dispersion state of the polymer alloy material changes.

  Since the thermosetting resin is generally an insoluble and infusible cured product, the thermosetting resin has very excellent characteristics such as solvent resistance or durability such as strength retention at high temperature. However, since the cross-linking reaction is formed by a covalent bond, there is a problem that it cannot be reprocessed, which is a major drawback in ensuring recyclability. An ionomer resin can be mentioned as the closest one to the recyclable thermosetting resin. This is obtained by adding a metal oxide or metal hydroxide such as magnesium oxide or calcium hydroxide to a polymer having a carboxyl group in the side chain. A pseudo cross-linking point is formed by forming an ionic bond between a metal and a carboxyl group. Although some improvement in heat resistance and toughness is observed with this method, it is significant due to the fact that the binding force between the metal compound and the carboxyl group is weak and the solubility of the metal compound in the resin is low, so that only a small amount can be added. No improvement in properties is observed.

Among thermosetting resins, polyimide resin has extremely high heat resistance and tough film performance, and is an industrially extremely useful material. As a method of processing polyimide into a film, it is common to form an imide ring by applying a polyimide solution and then heating at a high temperature. Moreover, once an imide ring is formed, the solubility in a solvent is significantly reduced. This feature is a significant drawback when recycling polyimide. Therefore, there is a demand for a material that can achieve both solubility in a solvent and high heat resistance, and a method for improving solubility in an organic solvent by copolymerizing a monomer having an aromatic nucleus substituted with a substituent such as alkyl. It has been known. However, a material having a glass transition temperature of 320 ° C. or higher has not been obtained by this method. In addition, this method has a problem that the price of the product is increased because the monomer is expensive.

It is more preferable.

  With the above configuration, heat resistance and flexibility can be imparted to the obtained pseudo-crosslinked resin composition. If this temperature condition is not met, there will be a problem that flexibility cannot be imparted at room temperature and thermal deformation will occur.

Hereinafter, it is preferable that the other is + 50 ° C. or higher, more preferably one is 0 ° C. or lower and the other is + 100 ° C. or higher.

Can do.

  The glass transition point can be measured as follows.

  Evaluation is made by measuring the glass transition point by DSC (differential scanning calorimetry). The DSC measurement is performed under the condition of a temperature increase rate of 10 ° C./min.

  By mixing the polymer A and the polymer B, a pseudo-crosslinked resin composition in which a hydrogen bond between polymer chains is newly formed to form a pseudo-crosslinked structure can be obtained.

  The pseudo-crosslinked resin composition of the present invention can be processed into a molding material, a sheet or a film. In this invention, when using a resin composition as a molding material, a sheet | seat, or a film, arbitrary components can be added as needed. For example, from the viewpoint of prevention of deterioration, thermal stability, moldability and processability, antioxidants such as phenols, phosphites and thioethers, aliphatic alcohols, fatty acid esters, phthalates, triglycerides, fluorine Surfactants, release agents such as higher fatty acid metal salts, other lubricants, plasticizers, antistatic agents, ultraviolet absorbers, flame retardants, heavy metal deactivators and the like may be added.

  In the present invention, a film or sheet can be obtained from the obtained polymer by volatilizing an organic solvent by a melt-kneading method or a solvent casting method.

  The casting conditions are not particularly limited, but can be performed at a temperature of 80 ° C. to 160 ° C., for example, in air or in an inert gas. Moreover, after performing preliminary drying using these conditions, it is possible to shorten a drying time by peeling off a film and drying this at high temperature of 160-350 degreeC.

  The obtained film or sheet is tough and flexible and has excellent mechanical properties. In addition, since the adhesiveness to a metal such as glass, aluminum, or copper is particularly high, selection of a cast substrate is important in the production of a film or sheet.

  Specifically, stainless steel, PET film, Teflon (registered trademark) film, and the like can be selected, but are not limited to these as long as the adhesion to the polymer is low.

  Examples of the optical component using the molding material, sheet or film obtained from the present invention include a CD pickup lens, a DVD pickup lens, a FAX lens, an LBP lens, an oligon mirror, and a prism.
