Title (EN) POLYPROPYLENE-BASED COMPOSITE
(FR) COMPOSITE À BASE DE POLYPROPYLÈNE
(KO) 폴리프로필렌계 복합재
Abstract:
(EN) The present invention provides a polypropylene-based composite capable of exhibiting impact strength characteristics, particularly, significantly improved impact strength characteristics at low temperatures, together with excellent strength characteristics, even without using a separate additive, by comprising (A) polypropylene and (B) an olefin-based polymer satisfying the following requirements, (b1) to (b4): (b1) density (d): 0.850 g/cc to 0.910 g/cc; (b2) melting index (MI, 190°C, 2.16 kg load conditions): 0.1 g/10 min to 100 g/10 min; (b3) molecular weight distribution (MWD): 1.5 to 3.0; and (b4) i) having two peaks in a temperature range of -20°C to 120°C for the measurement of temperature rising elution fractionation and ii) T(90)-T(50)≥60°C (where, T(90) is the temperature at which 90 wt% of olefin-based polymer is eluted and T(50) is the temperature at which 50 wt% of olefin-based polymer is eluted).
(FR) La présente invention concerne un composite à base de polypropylène capable de présenter des caractéristiques de résistance au choc, en particulier, des caractéristiques de résistance au choc significativement améliorées à basse température, ainsi que d'excellentes caractéristiques de résistance, même sans utiliser d'additif séparé, en comprenant (A) du polypropylène et (B) un polymère à base d'oléfine répondant aux conditions suivantes, (b1) à (b4) : (b1) densité (d) : 0,850 g/cc à 0,910 g/cc ; (b2) indice de fluidité à chaud (IFC, 190 °C, 2,16 kg de charge) : 0,1 g/10 min à 100 g/10 min ; (b3) distribution de poids moléculaires (DPM) : 1,5 à 3,0 ; et (b4) i) présentant deux pics dans une plage de températures de -20 °C à 120 °C pour la mesure du fractionnement par élution avec élévation de température et ii) T(90)-T(50) ≥ 60 °C (où T(90) est la température à laquelle 90 % en poids du polymère à base d'oléfine sont élués et T(50) est la température à laquelle 50 % en poids de polymère à base d'oléfine sont élués).
(KO) 본 발명에서는 (A) 폴리프로필렌, 및 (B) 하기 (b1) 내지 (b4)의 요건을 충족하는 올레핀계 중합체를 포함함으로써, 별도의 첨가제를 사용하지 않고도 우수한 강도 특성과 함께 충격 강도 특성, 특히 저온에서 현저히 개선된 충격 강도 특성을 나타낼 수 있는 폴리프로필렌계 복합재가 제공된다: (b1) 밀도(d): 0.850 g/cc 내지 0.910 g/cc, (b2) 용융지수(MI, 190℃, 2.16 kg 하중 조건): 0.1g/10min 내지 100g/10min, (b3) 분자량 분포(MWD): 1.5 내지 3.0, (b4) i) 온도상승 용리 분별 측정시 -20℃ 내지 120℃ 온도 범위에서 2개의 피크를 가지며, ii) T(90)-T(50)≥60℃ (여기서, T(90)은 올레핀계 중합체의 90중량%가 용출되는 온도이고, T(50)은 올레핀계 중합체의 50중량%가 용출되는 온도이다).
