Problems solved by technology

However, the invention of 3M Company has two serious problems: ① The compound has poor stability and is stored at room temperature, especially when it encounters light and moisture, it will quickly decompose by itself, making it difficult to preserve
②This compound is a liquid with extremely low viscosity, and the strength of the film layer will decrease when it is added to the photosensitive composition of the CTP plate, which will seriously affect the printing resistance
However, the etherified precursor in this technology is a single compound, so that the etherified ester and ether compounds are basically viscous, which is inconvenient to store and use.
When this compound is added to the photosensitive composition of the CTP plate, the strength of the film layer will decrease, which will affect the printing resistance and the layout of the plate.

Embodiment 1

[0018] Add 13g of carboxyl phenolic resin with code DF-10, 100mL of ether, 1.00g of phosphoric acid into a four-necked flask equipped with a stirrer, condenser, constant pressure dropping funnel and thermometer, and add 100ml of ethylene dropwise with a constant pressure dropping funnel Diethyl ether, after the dropwise addition, reacted at room temperature for 6 hours, washed with water, and dried in vacuo to obtain 12.6 g of a yellow solid, that is, carboxyl phenolic resin active ester and etherified product.

Embodiment 2

[0020] Add 5g carboxyl phenolic resin with code DF-10, 100mL 1,2-dichloroethane, 0.5g acetonyl triphenyl For phosphine bromide, add 60ml of vinyl ether dropwise with a constant pressure dropping funnel. After the dropwise addition, react at room temperature for 6 hours, wash with water, and dry in vacuo to obtain 5.1g of yellow solid, which is carboxyphenolic resin active ester and etherified product.

Embodiment 3

[0022] Add 6g of carboxyl phenolic resin whose code is DF-10, 100mL of dichloromethane, and 0.2g of acetonyl triphenylphosphine bromide to a four-necked flask equipped with a stirrer, condenser, constant pressure dropping funnel, and thermometer. Add 70ml of vinyl ethyl ether dropwise into the constant pressure dropping funnel. After the dropwise addition, react at room temperature for 3 hours, wash with water, and dry in vacuum to obtain 6.3g of yellow solid, which is carboxyphenolic resin active ester and etherified product.

Abstract

The invention discloses a synthesis of carboxylic phenol resin active ester and etherate in the technical field of functional high polymer material preparation. The synthesizing method is got through the reaction of carboxylic phenol resin, etherified reagent and catalyst. The synthesized carboxylic phenol resin active ester and etherate have higher light sensitivity, and can be used to the traditional PS edition, thermal sensitive CTP edition, photosensitive resist, electron beam resists or chemical amplitude resists and the like. Compared with the prior art, the synthesis does not need esterification in advance, carboxylic phenol resin is directly etherified under the function of catalyst, and the invention has high etherified ratio, excellent comprehensive property, excellent stability and convenient storage, and the product yield is solid.

Description

technical field [0001] The invention belongs to the technical field of polymer material preparation, in particular to the synthesis of carboxyl phenolic resin active ester and ether compound. Background technique [0002] In the invention patent (USP618212 (1990)) published by 3M Company in 1990, they used diphenylacetic acid and chloromethyl methyl ether, vinyl ethyl ether, dihydropyran, dihydrofuran and other active alkenes. Addition gives diphenyl acetate. This kind of ester is mixed with an acid generator, novolac resin and additives in a certain proportion, dissolved with an appropriate solvent, coated and dried, and the obtained resist coating will generate protonic acid in the exposed part after ultraviolet exposure, and it will be cured at room temperature. It can decompose the active ester of diphenylacetic acid, so that it can be developed with alkaline water to obtain an image, which can be used to make a positive PS plate or a positive photoresist. However, the...
