Patent number: 10913876Abstract: Provided herein are adhesive compositions comprising a polyurea-poly(meth)acrylate interpenetrating polymer network. Further provided are two-part curable adhesive compositions comprising a Part A initiator composition and a Part B activator composition. The Part A initiator composition comprises an organoborane-amine complex and the Part B activator composition comprises an isocyanate that is reactive with the amine portion of the organoborane-amine complex to liberate organoborane from the organoborane-amine complex. Further provided are methods of using an adhesive composition comprising a polyurea-poly(meth)acrylate interpenetrating polymer network, such as, for example, in joining and/or bonding together polyolefin materials (e.g., polypropylene random copolymer (PP-R) pipes).Type: GrantFiled: May 24, 2017Date of Patent: February 9, 2021Assignee: IPS CorporationInventors: Xiaoyi Xie, Andreas Schneider

Patent number: 10822715Abstract: Method for limiting growth of KDP-type crystals with a long seed where an upper and a lower ends of the long seed crystal are respectively limited by an upper baffle plate and a lower tray to restrain growth of a pyramidal surface and allow only four prismatic surfaces in [100] and [010] directions to grow. Finally grown crystal contains no pyramid-prism interface that severely restricts quality of optical element, and all cut optical elements have high optical quality. As four prismatic surfaces are subjected to highly similar growing environment and grow simultaneously, all optical elements cut therefrom have high optical uniformity. Due to uniqueness of a cutting angle of a KDP crystal frequency-tripled element, high cutting efficiency is achieved in the element, and an area of a maximum frequency-tripled element that may be cut is known in advance according to a horizontal size of the grown crystal.Type: GrantFiled: December 12, 2018Date of Patent: November 3, 2020Assignee: Shanghai Institute of Optics And Fine Mechanics, Chinese Academy of SciencesInventors: Hongji Qi, Duanyang Chen, Jianda Shao, Xiaoyi Xie, Bin Wang, Hu Wang
