But in the prior art, the organic / inorganic hybrid resin [such as: cage type polysilsesquioxane (POSS for short), polysiloxane, divinylsiloxane-bisbenzocyclobutene in bibliographical reports (referred to as DVS-bis-BCB) resins, etc.] still cannot meet the needs of the growing electronics industry. The thermal stability and low dielectric properties of the organic / inorganic hybrid resins of the prior art need to be further improved, and each performance can be tuned. Sex is not high

Embodiment 1

[0040] The preparation method of random copolymer [being called for short P (4-VBCB-co-St)], comprises the following steps:

[0041] Add 2.60 g (25 mmol) of styrene (St), 3.25 g (25 mmol) of 4-vinylbenzocyclobutene (4-VBCB) and 5 mL of dry Toluene and N-tert-butyl-N-(2-methyl-1-phenylpropyl)-O-(1-phenylethyl)hydroxylamine (0.5mmol) diluted in toluene in advance were added to the anaerobic bottle, and the mixture Freezing and pumping oxygen in a liquid nitrogen environment, and then thawing with nitrogen gas, repeat this cycle three times to ensure that the oxygen in the system has been removed. After the system returns to room temperature, raise the temperature to 90°C and stir for 18 hours, then raise the temperature to 120°C for 30 hours; after the reaction is completed, dilute the viscous reaction solution in tetrahydrofuran after the system returns to room temperature, and add the diluted solution drop by drop Precipitate in absolute ethanol, and filter the precipitate wi...

Abstract

The invention discloses a hydrolyzable siloxane-containing block copolymer represented by formula (I) and a preparation method thereof. The preparation method of the block copolymer is: mixing styrene and 4-vinylbenzocyclobutene Dissolve in toluene, add N-tert-butyl-N-(2-methyl-1-phenylpropyl)-O-(1-phenylethyl) hydroxylamine to mix, under inert atmosphere, at 90℃~120℃ Stir the reaction for 36-60 hours, and obtain the random copolymer after purification; dissolve the random copolymer in toluene, heat up to 90°C, add (4-vinylphenyl)trimethoxysilane, and heat at 90°C-120 Stirring and reacting at ℃ for 36-60 hours, and purifying by precipitation, the block copolymer containing hydrolyzable siloxane can be prepared; further providing a preparation method of silicon-based organic / inorganic hybrid resin. The product has excellent mechanical properties, electrical properties and thermal properties, and can be used as an interlayer dielectric packaging material for chips and circuit boards.

Description

technical field [0001] The invention belongs to macromolecule polymer and its preparation, and relates to block copolymer containing hydrolyzable siloxane, resin and its preparation method. The hydrolyzable siloxane-containing block copolymer and (silicon-based organic / inorganic hybrid) resin prepared by the invention are particularly suitable for use in integrated circuits as interlayer dielectric packaging materials for chips and circuit boards. Background technique [0002] Since the advent of the integrated circuit, it has been developing rapidly, not only pursuing high frequency, high speed, low power consumption and multi-function, but also shrinking its size. Today, integrated circuits have developed into ultra-large-scale integration with high integration, high density and high regularity. circuit (referred to as ULSI). Due to the continuous improvement of the performance and density of devices in ULSI, the feature size of the interconnection wiring structure has be...
