  • Patent number: 8652578
    Abstract: A method of forming a cured coating composition on an automobile component is provided. The method utilizes a coating compound including a radical polymerizable compound and an organoborane initiator and includes the step of applying the coating composition to the automobile component. The organoborane initiator is complexed with a bi-functional noncyclic blocking agent that has a carbon backbone and two organoborane complexing moieties. The two moieties are different from each other and are selected from the group of an amine moiety, a thiol moiety, and a phosphine moiety. In addition, the two moieties are separated from each other by two to four carbon atoms to increase the nucleophilicity of the blocking agent towards the organoborane initiator. The organoborane initiator is decomplexed from the blocking agent thereby forming a radical that is used to polymerize the radical polymerizable compound and cure the coating composition on the automobile component.

    Abstract: An application to a resin material and a polymerization method of a polymerization agent having a polymerizable surface structure and a mechanism of supplying the polymerization agent, the polymerization agent exhibiting a polymerizing function in contact with the surface of the resin material. The resin material is obtained by living radical polymerization of a radical polymerization initiator exhibiting living property and an unsaturated monomer capable of radical polymerization with the polymerization initiator. The polymerization agent is brought into in contact with the surface of the resin material to induce radical re-polymerization of the polymerization agent. As a result, a damaged portion of the resin material can be repaired or the resin materials can be bonded to each other by way of the polymerization agent, which can suppress formation of the hetero-interface or improve the service life of the resin material.

  • Patent number: 7332559
    Abstract: A method of preparing a high molecular weight polycarbonate resin is provided. In the method, a condensation polymerization process is used so that a mole fraction of arylcarbonate existing in a terminated group of a reaction side product having a degree of polymerization of less than 3 obtained as a result of transesterification and in a non-reacted diarylcarbonate is reduced. As a result, a high molecular weight polycarbonate can be obtained by solid state polymerization. A polycarbonate with an identical molecular weight can be produced in a substantially short time, compared with a polycarbonate produced through solid state polymerization without condensation polymerization. In addition, the non-use of a poisonous phosgene contributes to stability. Furthermore, quality polycarbonate may be guaranteed.
