The present invention relates to a process for the manufacture of foamed polymeric material characterised by the presence of two or more cellular layers and aggregates that exhibit variations in cell size and cell density distribution. The heterogeneous polymeric material is foamed using a single expansion step, thus eliminating the assembly steps and improving the mechanical proprieties of the foam. The invention allows producing custom foam with predefined profiles of cell size, cell density distribution, and with correlated variations of its physical properties. The key to this invention is that the polymer material before expansion is made in multiple polymerisation steps from the original monomers. In each polymerisation step, a different recipe of monomers and physical blowing agents' concentration is used. These recipes within the final polymer material will expand under the same temperature to produce various aggregates of cell sizes and cell distribution in the final foam.

The present invention provides a method to prepare polymer materials with interlocked porous structures by freezing and demulsification, which includes: (1) Preparing an emulsion containing uncrosslinked polymers and crosslinking agents. The uncrosslinked polymers are presented in the organic phase, and the crosslinking agents are presented in the organic phase or water phase. Under freezing, the demulsification is occurred which leads to the interaction between polymers and crosslinking agents, and the crosslinked materials are obtained. (2) After removing the ice crystals, polymer materials with interlocked porous structures are synthesized. The method provided by the present invention is simple to operate, and can well adjust the porous structures of obtained porous polymer materials. In addition, it is suitable for large scale manufacturing. At the same time, this process can form different functional porous polymer materials by simply changing the used monomers. Particularly, it can prepare melt-blown fabrics with antibacterial property, high-throughput vertical porous structures and high-temperature sterilizable feature, therefore, it can be used to manufacture medical products such as masks.

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.
