Abstract: A solid-phase synthesis carrier, a preparation method therefor and the use thereof, wherein a diene cross-linking agent with a similar reactivity ratio to styrene and two vinyl groups thereof not on the same benzene ring is selected as a cross-linking monomer, and is subjected to suspension polymerization to obtain a porous resin. The porous resin is then functionalized to obtain a porous resin with an amino or hydroxyl functional group. Compared with existing preparation methods, the reactivity ratio of the cross-linking agent and styrene is similar, which is beneficial to improving the uniformity of the chemical structure in the resin, forming uniformly distributed active sites and channels, and is beneficial to improving the reaction efficiency and reducing the mass transfer resistance. The preparation of oligonucleotides by using such a carrier as a solid-phase synthesis carrier can improve the yield and purity of the oligonucleotides.

Abstract: A porous resin used to solid phase synthesis and a preparation method therefor, specifically being a porous resin having functional groups being an amino group or a hydroxyl group and a preparation method therefor. Using an olefin compound containing two cyano groups as a modified monomer, using a high internal phase emulsion as a pore-foaming agent, and performing suspension polymerization to prepare the porous resin. And then functionalizing the porous resin to obtain the porous resin having functional groups being an amino group or a hydroxyl group. Different from the existing preparation method, the modified monomer can make the distribution of the functional groups more uniform, and make the swelling degrees of the porous resin in different solvents close. The high internal phase emulsion pore-foaming agent can make the pore size distribution of the carrier narrower. The porous resin can be used as a solid phase synthesis carrier to prepare an oligonucleotide, and the use of the carrier is beneficial for improving the yield and purity of the oligonucleotide.

Abstract: The present invention relates to an adsorbent resin for removing perfluorinated pollutants from a body of water, a preparation therefor and the use thereof. The objective is to solve the problem of traditional adsorbent materials, such as active carbon materials, having a poor effect in terms of removing perfluorooctanoic acid from water, being non-renewable, etc. In the present method, styrene and divinylbenzene are used as framework materials, a suitable pore-forming agent and a suitable dispersant are selected in order to prepare a macroporous resin with a moderate pore size, and an alkylation reaction is carried out at a low hindrance with p-xylylene dichloride (XDC) being used as a post-crosslinking agent, whereby a rigid benzene ring structure is introduced into the resin by means of post-crosslinking, thereby further increasing the hydrophobicity of the resin and increasing the crosslinking degree thereof; in addition, the micropore structure is adjusted in order to obtain an adsorbent resin with a narrow particle size distribution, a uniform pore size and a high specific surface area. The size of micropores in the resin is close to the molecular size of perfluorooctanoates in water, the adsorbate sieving capacity is strong, and the adsorption rate of perfluorinated compounds can be further improved.
