标题:Synthesis of amphiphilic block copolymers and polymeric nanofibers produced therefrom
发明人:ZETTERLUND PER B; ISHIZUKA FUMI; KIM HYUN JIN; CHATANI SHUNSUKE; NIINO HIROSHI
权利人:NEWSOUTH INNOVATIONS PTY LTD
摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人:URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.

标 题:Synthesis of latex capsules
发明人:BLANKENSHIP ROBERT M; NOVAK RONALD W; NEYHART CLARENCE J; VOGEL MARTIN
权利人:ROHM & HAAS
摘要:The present invention is concerned with core and shell polymeric particles having microvoids in the core and one or more channels connecting the microvoids to the exterior of the particle. These particles, or LCAPs are produced by forming a core of polymeric acid, encasing the core in a shell polymer permeable to base, and then neutralizing the core such that the core swells, causing the shell to 'explode' in a controlled fashion. This controlled explosion causes channels to form in the shell. n These particles can be used as control release devices for target compounds, to impart reinforcing properties to acrylic films, as an opacifying agent in coating compositions, and as a supplement or replacement of part or all of the pigmentary material or extenders that would otherwise be used in such coating compositions.

标题 :Binder for positive electrode plate and synthesis method therefor, positive electrode plate comprising same, secondary battery and electric device
发明人:YE CHONG; SUN CHENGDONG; ZHENG YI; XIE LAIYONG
权利人:CONTEMPORARY AMPEREX TECHNOLOGY CO LTD
摘要:Provided in the present application are a binder for a positive electrode plate and a synthesis method therefor, a positive electrode plate comprising same, a secondary battery and an electric device. The binder comprises a copolymer formed by comonomers, wherein the comonomers comprise a first monomer, a second monomer, a third monomer, and a fourth monomer, and the molar content of the first monomer is 3 mol% to 10 mol% based on the total molar amount 100 mol% of the comonomers. The binder provided in the present application not only has good flexibility and high cohesiveness, but also has good electrolyte swelling resistance, such that a positive electrode plate is ensured to have a high bonding strength and good processing properties, and a secondary battery is also ensured to maintain a good structural stability during the long-term charging and discharging processes, which further gives full play to the electrochemical properties of the secondary battery.
