ABSTRACT A novel aromatic diamine‐based benzoxazine monomer (PDETDA) was successfully prepared from diethyltoluenediamine (DETDA), phenol, and paraformaldehyde through a simple one‐step solvent‐less method. The structure of PDETDA confirmed by FTIR, 1 H NMR, 13 C NMR. curing behavior studied DSC, rheological measurement. results showed that the alkyl substituents on benzene ring in DETDA not only facilitated synthesis effectively hindering formation triazine network, but also endowed with...
The effect of successive self-nucleation and annealing (SSA) parameters including the time ts, temperature interval heating cooling rates on crystallization properties polypropylene were researched in detail. Based those results, behavior sequence length distribution with different isotacticity propylene/1-butene copolymer 1-butene comonomer content prepared by Ziegler–Natta catalyst studied through SSA. With increase polypropylene, gradually increases. propylene bulk polymerization has...
Abstract A series of star block polymers with a hyperbranched core and 26 arms are successfully synthesized by atom transfer radical polymerization styrene (St), poly(ethylene glycol) methyl ether methacrylate from polystyrene (HBPS) multifunctional initiator. All‐solid polymer electrolytes composed these multiarm lithium salts prepared. The influences polyoxyethylene (PEO) side‐chain length, PEO content, salt concentration type, the structure on ionic conductivity systematically...
Abstract Developing thermosets derived from renewable sources is of great importance. In this work, a fully bio‐based benzoxazine monomer, 3,6‐bis((3‐(furan‐2‐ylmethyl)‐3,4‐dihydro‐2 H ‐benzo[ e ][1,3]oxazin‐6‐yl)methyl)piperazine‐2,5‐dione (TCDPF), conveniently synthesized L‐tyrosine cyclic dipeptide (TCDP), furfurylamine and paraformaldehyde. The chemical structure TCDPF confirmed by nuclear magnetic resonance spectroscopy Fourier transform infrared (FT‐IR) techniques. curing behavior...
ABSTRACT A novel aromatic diamine‐based benzoxazine (P‐ m PDA) is successfully synthesized from ‐phenylenediamine ( ‐PDA), 2‐hydroxybenzaldehyde, and formaldehyde. The polymerization behavior of P‐ PDA the properties its thermoset are studied. results indicate that owns favorable processability including low temperature, liquefying wide processing window. Even lower temperature (polymerization onset as 80 °C) can be achieved by promotion catalysts. ring‐opening first generates...
Abstract The effects of different mixed external donors on the crystallization behavior and sequence length distribution polypropylene prepared by MgCl 2 ‐supported TiCl 4 Ziegler–Natta catalyst were studied through successive self‐nucleation annealing (SSA) technique. SSA results show that ability relative contents long isotactic gradually increase with component Donor‐1 (cyclohexylmethyldimethoxysilane, dicyclohexyl(dimethoxy)silane, dipiperidinedimethoxysilane) in when ratio donors/Ti...
Benzoxazines containing various additional functional groups have been extensively reported to improve the properties of polybenzoxazines. In this work, a novel amino‐containing benzoxazine (PDETDA‐NH 2 ) was conveniently synthesized from diethyltoluenediamine (DETDA), 2‐hydroxybenzaldehyde, and paraformaldehyde used as hardener for diglycidyl ether bisphenol‐A (DGEBA). The curing behaviors PDETDA‐NH /DGEBA systems were studied by DSC, FT‐IR, 1 H NMR. When curing, firstly polymerized N,O...
With the rapid development of hydraulic technology, type and performance motor are put forward higher requirements. In actual working condition, needs to have more than one stable torque output, but existing cannot be realized. order solve this problem, a series new motors based on double rotor structure developed, thus further developing multi-speed with equal width curve eccentric shell. One stator two rotors cooperate each other enter through different inputs. The connection oil outlet...
