[0081] Wherein,...

Embodiment 1

[0105] A preparation method of modified polybutadiene resin, comprising the following steps:

[0106] In a dry and clean 100mL flask, drop into polybutadiene resin (PB resin) 5g (0.0833mol), 4-bromobenzophenone 8.7g (0.0333mol), palladium carbon catalyst 2.61g, triethylamine 6.74g ( 0.0666mol) and N,N-dimethylformamide 36.00g, under a nitrogen atmosphere, reflux at 130°C for 16h, track the reaction process by thin layer chromatography (TLC), the PB resin of this embodiment has the following structure:

[0107]

[0108] Among them, Y is 5;

[0109] M is 55;

[0110] After the reaction was completed, the reaction solution was cooled to room temperature, and the insoluble impurities in the reaction solution including catalyst were removed by high-speed centrifugation, and then precipitated in methanol with 5 times the volume of the reaction solution, stirred for 30 minutes, and suction filtered to obtain an off-white solid;

[0111] Dissolve the obtained off-white solid in t...

Embodiment 2

[0114] The difference between this example and Example 1 is that in this example, 5.27 g (0.0666 mol) of pyridine is used to replace the triethylamine in Example 1, and 36 g of N-methylpyrrolidone is used to replace the N,N-diethylamine in Example 1. Methylformamide, in this example, reflux at 145°C for 18 hours under a nitrogen atmosphere, other reaction raw materials, their dosages, and reaction steps are the same as in Example 1, to obtain a modified polybutadiene resin;

[0115] The characterization and test method of the present embodiment modified polybutadiene resin are the same as embodiment 1, and the proton nuclear magnetic spectrum (abscissa ppm) that obtains is as image 3 As shown, the peak corresponding between 7.25~7.75ppm is the characteristic peak of the benzene ring group, which proves that the grafting reaction of the present embodiment is successful; DSC test result is as follows Figure 4 Shown, showed that the glass transition temperature of the modified ...

Abstract

The invention provides modified polybutadiene resin as well as a preparation method and application thereof, and relates to the technical field of high polymer material modification. The modified polybutadiene resin is obtained by introducing an aromatic group to a side chain double bond of polybutadiene resin; therefore, on the basis of not changing the original dielectric property, mechanical property and chemical resistance of polybutadiene, the glass transition temperature of the polybutadiene resin is greatly increased, and the application range of the polybutadiene resin is expanded. Thus, the technical problem of low glass-transition temperature of polybutadiene resin is solved, and the technical effect of greatly increasing the glass-transition temperature of polybutadiene on the basis of not changing the original dielectric property, mechanical property and chemical resistance of polybutadiene is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a modified polybutadiene resin and its preparation method and application. Background technique [0002] In recent years, with the rapid development of emerging communication technologies such as 5G high-frequency and high-speed communication, the upgrading of related products and the reform and innovation of production technology are also accelerating. [0003] At present, the traditional printed circuit board (PCB) can no longer meet the performance requirements of the electronic and electrical industry. The requirement of PCB is to have excellent comprehensive properties such as mechanical properties, mechanical properties and aging resistance while satisfying electrical properties. Copper-clad laminate (CCL), the basic material of PCB, plays a vital role in the performance of PCB, and CCL is composed of resin, glass cloth and copper foil, among which re...
