Oxime cross-linked biocompatible polymer hydrogels and methods of use thereof
Methods and hydrogels for preventing or reducing cellular adhesion and protein adsorption to a tissue (e.g. cardiac tissue) are disclosed. The hydrogels generally include at least three component polymers, a first polymer including an aminooxy group, a second polymer including a reactive oxo group, that are cross-linked by oxime bonds and a third polymer including a catechol group, that causes better retention on the cardiac tissue. The hydrogels are suitable for binding to and coating a tissue or cell. The hydrogels operate to reduce cellular adhesions and protein adsorption to the tissue or cell.

Core and shell polymers for 3D-printing
A core/shell polymer material suitable for three-dimensional printing is provided. The core/shell polymer material may include at least one amorphous polymer as a core particle and at least one semicrystalline polymer as a shell material surrounding the core particle.
Self-hardening organic synthetic resin mixture used for additive manufacturing, and application therefor
The present invention relates to organic polymer synthetic materials, and discloses a self-curing organic synthetic resin composition for additive manufacturing. The self-curing organic synthetic resin composition includes 30-75% by weight of a linear thermoplastic phenolic resin and 25-70% by weight of a phenol modified furan resin. The self-curing organic synthetic resin composition is prepared through three stages. The linear thermoplastic phenolic resin prepared in stage (1) and the phenol modified furan resin prepared in stage (2) are mixed in a certain weight ratio in stage (3) to obtain the self-curing organic synthetic resin composition for additive manufacturing, which has the advantages of high strength at normal temperature, excellent resistance to high temperature, high activity and excellent collapsibility. Thus, the self-curing organic synthetic resin composition provided in the invention is suitable for additive manufacturing, and particularly for 3D printing in mold casting.
POLY(PHENYLENE ETHER) BASED COMPATIBILIZING MATERIAL
Compatibilizing materials for use with fibers and polymeric compositions are described. A compatibilizing material can include a silane (Si) modified polyphenylene ether (PPE) oligomer having a resin reactive functional group. The resin reactive functional group can be between the PPE moiety and a Si moiety. In other instances, the resin reactive functional group can be a substituent of the Si moiety.
