摘要： Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

摘要： This application relates to a production method for a medical balloon that can suppress the occurrence of the symptom of delayed-type allergy (Type IV) in addition to immediate-type allergy (Type I). The production method includes molding a composition containing a carboxy-modified conjugated diene polymer, a vulcanizing agent, and a xanthogen compound into the shape of a balloon. The molding of the composition into the shape of a balloon includes dipping a balloon-shaped mold in the composition in the form of latex.

摘要： The present invention discloses a film for a medicine packaging and a method of preparing the same. The film for the medicine packaging includes a polymer film layer, a graphene composite layer and a light-curable adhesive, wherein the polymer film layer is bonded with a graphene composite layer by a light-curable adhesive, the graphene composite layer includes multiple graphene layers bonded by the light-curable adhesive; and the light-curable adhesive includes a hyperbranched cationic mussel-imitated polymer including a multi-hydroxylbenzoylbenzamide ene amide monomer, a cationic monomer and a photo-responsive monomer. The present invention provides strong adhesion with reduced adhesive layer, allowing greatly increasing the number of the graphene layers in the graphene composite layer without obvious increase in the total thickness and mass. This can meet the requirements of the medicine packaging material, as it obviously lowers the film's permeation to water vapor and oxygen and significantly enhances the tensile strength.

摘要： Silicone-based pressure-sensitive adhesives, reaction mixtures used to form the pressure-sensitive adhesives, methods of making the silicone-based pressure-sensitive adhesives, and articles containing the silicone-based pressure-sensitive adhesives are described. More particularly, the silicone-based pressure-sensitive adhesives include silicone-based elastomeric materials that are prepared by polymerizing a silicone compound having at least two ethylenically unsaturated groups in the presence of actinic radiation (e.g., ultraviolet radiation) and a controlled radical initiator. The controlled radical initiator is a bis-dithiocarbamate or bis-dithiocarbonate compound having a single carbon between the two dithiocarbamate or dithiocarbonate groups.
