| MMA, titanium(III)–salicylaldoxime
[Ti(IIII)-SAO], 2.0 wt % HQ |
observation
on termination of polymerization initiated by the [Ti(IIII)-SAO] redox
system |
the mechanism
of termination was predominantly reciprocal coupling, with a minor
contribution from a chain transfer process that involves solvent molecules |
polymerization time (90
min): |
(27) |
| absence of HQ: 80% conversion |
| presence of HQ: 40% conversion |
| PMMA, polypyrole dodecylbenzenesulfonate
(PPY.DBSA), 1.0 wt % HQ |
HQ as compatibilizer agent
to increase the dispersibility of PPY.DBSA with PMMA |
in the presence of HQ, optical
micrographs indicated a moderate amount of phase separation |
the thermal events in the
blends containing HQ exhibit substantial temperature shifts, indicating
more mixing and miscibility than the comparable processes in pure
polymers |

| PMMA bone cement, rifampin
(RIF) 1.00 (1.2 × 10–3), HQ 0.13 (1.2 × 10–3) g(mol) |
characterize the
effect
of HQ and HQ in RIF incorporation intoPMMA bone cement |
the HQ structure of RIF
was discovered as the polymerization inhibitor based on the radical
scavenging experiment and strength testing |
compared to the control,
RIF had much lower strength and remained well below 70 MPa for 14
days, and HQ had lowest moduli |

(UHMWPE), BPO, MMA, PMMA, 300 ppm of HQ |
improving standard
PMMA bone cement’s poor mechanical characteristic |
tensile strength
value is improved for PMMA bone cement with HQ and BPO compared to
the pure PMMA bone cement |
tensile strength (MPa): |
(34) |
| BPO 0.75%, HQ 300 ppm: 49.9 ± 3.75 |
