Preparation method of monomer composition

Abstract

The invention relates to a monomer composition and a preparation method and application thereof, in particular to a monomer composition mainly comprising a (methyl) acrylic acid dicyclo-pentenyl ester. However, the (methyl) acrylic acid dicyclo-pentenyl ester and dicyclo-pentadiene have repulsive foul smell which affects the application of the (methyl) acrylic acid dicyclo-pentenyl ester, the dicyclo-pentadiene and the polymer thereof. The invention combines the (methyl) acrylic acid dicyclo-pentenyl ester and the dicyclo-pentadiene with a low-grade saturated fatty acid dicyclo-pentenyl esteraccording to proper proportion, thereby reducing or removing the foul smell, and opening up a wide way for the popularization and application of the monomers and polymers which are disused due to thefoul smell. The monomer composition has simple and easy preparation and low cost, and the polymer is odorless.

Description

technical field [0001] The present invention relates to a monomer composition and its preparation method and application. More specifically, it is a composition mainly composed of biscyclopentenyl (meth)acrylate. Background technique [0002] Dicyclopentenyl (meth)acrylate [DCP(M)A] is prepared by the addition of (meth)acrylic acid and dicyclopentadiene (DCP) under the catalysis of boron trifluoride ether complex . [0003] Dicyclopentadiene is the C of ethylene engineering 5 with C 9 The by-products in the distillate also have a large amount of existence in the unhydrogenated pyrolysis gasoline and the light coal tar of the coking by-product in the refinery engineering, which provide potentially abundant and cheap raw materials for the synthesis of [DCP(M)A]. The cost of [DCP(M)A] monomer creates favorable conditions. The [DCP(M)A] monomer molecule contains easily polymerizable acrylate double bonds and difficultly polymerizable cyclopentene double bonds, as well as al...

Problems solved by technology

The [DCP(M)A] monomer molecule contains easily polymerizable acrylate double bonds and difficultly polymerizable cyclopentene double bonds, as well as allyl hydrogen that is prone to free radical degeneration chain transfer, so that the polymerization of this type of monomer The reaction is very characteristic, and its polymer is colorless and transparent, with high glass transition temperature and hardness, but this monomer and the dicyclopentadiene used in its synthesis have a sensitive odor. No matter in the process of synthesizing or using this type of monomer, it will have a great impact on operators and the environment, and the polymer formed by this type of monomer also has a residual odor for a period of time, thus, at home and abroad, making People refuse or even give up the use of this type of monomer, which affects the development and application of this type of monomer and its products
