Problems solved by technology

Because the polyamine and guanidinium salt polymer described in CN1282698C only contain a kind of methylene structure, therefore can't take into account antibacterial effect and biocompatibility simultaneously when using as a kind of antibacterial agent, that is to say, when this polyamine When the antibacterial effect of the guanidinium salt polymer is improved, there is a higher risk of harm to the human body; and when it is safe for the human body, the antibacterial effect is not good
In addition, the double bond activity on this larger molecule is not high, which will lead to inefficiency in the free radical grafting reaction with the polyolefin matrix, so most of the polyamines and guanidinium salt polymers cannot be chemically bonded. Linked with the polyolefin matrix, it only exists in the polyolefin matrix in a free form. When this polyamine and guanidinium salt polymer precipitates on the surface of the polyolefin, there is a risk of human injury

Abstract

The invention relates to a preparation method of a multifunctional vinyl polymer, which comprises the following two steps: A, in the presence of initiator, performing grafting reaction on an alkene monomer containing multiple functional groups and a vinyl polymer under the synergetic effect of a second olefin monomer, thus preparing a functional vinyl polymer; and B, reacting copolycondensate with the functional vinyl polymer, thus preparing the multifunctional vinyl polymer. By adopting the preparation method provided by the invention, the grafting efficiency of the copolycondensate and the vinyl polymer can be greatly improved, and the structure of the copolycondensate can be regulated, so that the prepared multifunctional vinyl polymer has affinity with modified matrix resin, and also has antistatic effect, anti-harmful microbe effect and favorable biocompatibility. The multifunctional vinyl polymer can be used as an antistatic agent master batch, an anti-harmful microbe master batch and a compatilizer master batch, or be used as a modifier master batch for providing dyeing for synthetic fibers.

Description

technical field [0001] The invention relates to chemical products, in particular to a preparation method and application of a multifunctional vinyl polymer. Background technique [0002] Antistatic agents traditionally used in industrial production generally use small-molecule surfactants. Surfactants are amphiphilic compounds that contain both hydrophilic and lipophilic groups in their molecular structure, and are generally added by blending. Into the polymer, enriched on the surface of the polymer by migration, so as to eliminate static charge, or reduce surface friction, so that it does not generate too much static charge, so as to achieve the purpose of antistatic. For example, CN100410306C discloses a sulfonate phosphonium salt formed by a specific organic sulfonate anion and an organic phosphonium cation as an essential component, and a substance containing alkali metal ions and / or alkaline earth metal ions at a total concentration of 0.1 to 300 ppm as Antistatic agen...
