して銅張基板を得た。基板の特性を表1に示す。 There are polymaleimides represented by the following structural formulas, and these can be used alone or in a mixture of two or more. The mixture of polyimide (A) and polymaleimide (B) is preferably used in an amount of 10 to 50% by weight, more preferably 15% by weight based on the amount of polymaleimide (B) and polyimide (A).
~30% by weight. Polymaleimide (B) is 10% by weight
If it is less than 50% by weight, the curing will not be sufficient, and if it is more than 50% by weight, the resin composition will become brittle and have no moldability. Mixing of polyimide and polymaleimide may be carried out in powder form, but it is usually carried out by adding and dissolving the polymaleimide in a polyimide varnish dissolved in a solvent such as DMF. The thus obtained mixed varnish of polyimide and polymaleimide is cast onto a glass plate, stainless steel plate, etc. and dried to obtain an adhesive film.
The drying temperature and time vary depending on the solvent used and the type of polymerimide, but the temperature needs to be kept lower than the temperature at which the reaction of the polymaleimide becomes noticeable, and the drying time is set so that the amount of residual solvent is about 1% or less. must be done. The obtained adhesive film is laminated on an adherend and then heated and pressed at a temperature above the softening point, thereby making it possible to obtain a molded article with excellent heat resistance and good adhesive strength. Since the adhesive film according to the present invention is highly flexible, it is suitable as a heat-resistant film adhesive for a copper foil of a flexible wiring board. The present invention will be explained in detail below with reference to Examples, but the present invention is not limited to these Examples. Example 1 EBTA41.0g, m-APPS21.6g, 2,4-
DAT6.1g, stirrer, thermometer, nitrogen gas introduction tube,
The mixture was placed in a four-necked flask equipped with a cooling tube, and 618 g of m-cresol and 108 g of toluene were added thereto, followed by heating and stirring while flowing nitrogen gas. The reaction was carried out at 150 to 160°C for 16 hours to obtain a polyimide varnish with a resin content of 19.2% and a viscosity of 16P. This polyimide varnish was poured into acetone, reprecipitated, crushed, washed, and dried to obtain polyimide powder. The reduced viscosity of polyimide powder (concentration 0.1 g/dl, solvent N,N-dimethylformamide (DMF), temperature 30.0°C) is 0.65
It was dl/g. 100g of obtained polyimide powder
A varnish was obtained by dissolving 10 g of N,N'-(4,4'-diphenylmethane) bismaleimide (BMI) in 400 g of DMF. This varnish was cast onto a glass plate, dried at 130℃ for 10 minutes, peeled off, and fixed on an iron frame.
An adhesive film was obtained by drying at 200°C for 1 hour. The resulting adhesive film had a thickness of 25 μm and a residual solvent amount of 1
%, had a softening point of 220°C, and had excellent flexibility without cracking even when bent at 180°C. Example 2 Example 1 except that 20 g of BMI-M (polymaleimide manufactured by Mitsui Toatsu Chemical Co., Ltd.) was added instead of N,N'-(4,4'-diphenylmethane)bismaleimide.
An adhesive film was obtained in the same manner as above. The resulting adhesive film had a thickness of 25 μm, a residual solvent content of 1.1%, and a softening point.
The temperature was 225°C, and it did not crack even when bent at 180° and had excellent flexibility. Comparative Example 1 A varnish prepared by dissolving 100 g of Kerimide 601 (polyamino bismaleimide resin manufactured by Nippon Polyimide Co., Ltd.) in 100 g of DMF was cast onto a glass plate and dried at 130°C for 10 minutes and then at 170°C for 20 minutes, but the film was brittle and did not form. It didn't happen. Examples 3 to 5 and Comparative Example 2 Adhesive films obtained in the same manner as in Example 1 except that the BMI amount in Example 1 was changed as shown in Table 1.
A copper-clad board was obtained by sandwiching a mm-thick aluminum plate and a 35-μm-thick single-sided roughened copper foil and laminating them at 50 kgf/cm 2 at 275° C. for 30 minutes. Table 1 shows the characteristics of the substrate.
