Abstract: The present invention relates to a large-sized vinyl chloride seed with an average particle size of 0.65 to 1.5 ?m, a vinyl chloride resin with improved low-viscosity properties, and preparation methods thereof. The preparation of the large-sized vinyl chloride seed includes adding a vinyl chloride monomer, an emulsifier, and a polymerization initiator to an aqueous medium; homogenizing the mixed solution using a rotor-stator type homogenizer; and subjecting the resultant monomer droplets to a polymerization reaction.

Abstract: Provided is a high-repetition-rate femtosecond regenerative amplification system. The regenerative amplification system includes: a laser oscillator emitting pulses; a stretcher stretching the pulses with negative dispersion; a regenerative amplifier amplifying the pulses, the regenerative amplifier comprising an acousto-optic modulator for pulse switching, a pulsed pump laser for pumping a gain medium, a resonator for reciprocating the pulses between a plurality of mirrors, and at least one chirped mirror for providing negative dispersion; and a glass compressor compressing the pulses. Accordingly, the 100 kHz-class high-repetition-rate femtosecond regenerative amplification system can produce an output energy of tens of ?J, higher than a few ?J provided by a conventional system.
