preparation example Construction

[0027] One, the preparation method of acrylate polymer:

[0028] Under the conditions of stirring and nitrogen protection, thermal polymerization reaction of thermal initiator benzoyl peroxide and acrylate mixture with a monomer content of 0.1-3% in a toluene solution with a concentration of 30-70% An acrylic polymer; wherein, the polymerization temperature is 65-100° C., and the polymerization time is 3-10 hours.

[0029] The above-mentioned acrylate is ethyl acrylate, or butyl acrylate, or glycidyl methacrylate, or octyl acrylate, or acrylic acid, or lauryl acrylate, or octadecyl acrylate, or hydroxyethyl acrylate, or hydroxy acrylate Propyl ester, or propyl acrylate, or at least any one of methyl acrylate.

Synthetic example 1

[0031] Ethyl Acrylate (25% by weight), Butyl Acrylate (20%), Glycidyl Methacrylate (5%), Octadecyl Acrylate (5%), Hydroxyethyl Acrylate (20%), Methyl Acrylate A total of 100 grams of ester (25%) was added in 100 grams of toluene, 0.1 gram of benzoyl peroxide was added, the temperature was raised to 80° C., and the product was used for further reaction after 10 hours of reaction.

Synthetic example 2

[0033] Octyl Acrylate (30%), Butyl Acrylate (20%), Glycidyl Methacrylate (10%), Lauryl Acrylate (5%), Hydroxypropyl Acrylate (20%), Propyl Acrylate (15%) %)) was added into 50 grams of toluene in total, 0.5 gram of benzoyl peroxide was added, the temperature was raised to 65° C., and the product was used for further reaction after 6 hours of reaction.

Abstract

An acrylic ester polymer and its synthesis are disclosed. The process is carried out by heat polymerizing for mixture of thermal initiator benzoyl peroxide and acrylic ester under agitation and nitrogen protection to obtain acrylic ester polymer, adding into acrylic acid, taking tosylate as catalyst and hydroquinone as inhibitor, reacting at 100-110 degree, removing water, decompressing, and removing solvent and inactive raw material to obtain final product. It can be used to machine building material cyanamide paper, and improve coating and substrate performances and adhesion.

Description

technical field [0001] The invention belongs to the field of environment-friendly photosensitive macromolecular materials, and in particular relates to the formulation of free radicals and cationic photopolymerization systems and the synthesis of special additives. Background technique [0002] Photopolymerization is the use of light as the reaction power, through the light acting on light-sensitive compounds, so that a series of photophysical and photochemical reactions occur to generate active substances, thereby initiating the polymerization of active monomers, and finally converting the liquid resin into solid polymer material. Its polymerization is characterized by energy saving, environmental friendliness, cost-effectiveness, compact photopolymerization device, and high production efficiency. In addition, photopolymerization has outstanding advantages compared with traditional polymerization techniques, such as room temperature polymerization, which is beneficial to t...
