Problems solved by technology

However, the vinyl structure selected by the resin has the following problems: 1. For the allyl group, due to the conjugation of its free radical intermediate, it does not have the activity of free radical curing; 2. For the acryloyl and methacryloyl groups, due to this The two vinyl active groups contain a certain polar carbonyl chemical structure, which will cause the dielectric constant and dielectric loss of the prepared substrate to increase; 3. For isobutenyl and vinyl, although they do not contain polar chemical structures, isobutylene radicals and vinyl groups need to initiate polymerization under the condition of peroxide radical initiators, and peroxide radical initiators are polar, which will increase the dielectric constant and dielectric loss of the substrate
However, the base material prepared by the composition containing vinylbenzyl ether modified poly(p-hydroxystyrene-styrene) polymer resin has high crosslinking density and high brittleness, which cannot meet the toughness requirements of copper clad laminates, so it is also necessary to Improvement of brittleness of poly(p-hydroxystyrene-styrene) polymer resin composition modified with vinylbenzyl ether

Abstract

The present invention relates to a vinyl benzyl ether modified poly(p-hydroxystyryl-styrene) polymer resin composition, comprising: (1) a vinyl benzyl ether modified poly(p-hydroxystyryl-styrene) polymer resin; (2) an olefin resin in which the weight ratio of butadiene having a 1,2-addition in the molecular structure is not less than 20%. The present invention also relates to a prepreg comprising the resin composition and an application thereof in a high frequency circuit board; a substrate prepared by using the resin composition has a low dielectric constant, low dielectric loss, a low thermal expansion coefficient and like comprehensive properties, and the area of a "+"-shaped drop mark formed on the substrate under a falling weight impact load is small, while the substrate has good toughness, and may satisfy the requirements for toughness of a copper-clad board.

Description

technical field [0001] The invention relates to the technical field of copper-clad laminates, in particular to a resin composition and its application in high-frequency circuit boards, in particular to a vinyl benzyl ether modified poly(p-hydroxystyrene-styrene) polymer Resin composition and its application in high frequency circuit board. Background technique [0002] In recent years, with the rapid development of wireless communication technology and electronic products, electronic circuits have entered the stage of high-speed information processing and high-frequency signal transmission; however, when the frequency is greater than 300MHz, or even above GHz, the electrical properties of the substrate will be seriously affected. The characteristics of electronic circuits put forward higher requirements on the performance of substrates. [0003] In terms of dielectric constant performance, in high-frequency circuits, the transmission rate of the signal is related to the die...
