Title (EN) CAMERA LENSES PREPARED FROM THERMOPLASTIC COMPOSITIONS HAVING HIGH FLOW AND DUCTILITY, AND METHOD OF PREPARING CAMERA LENSES
(FR) OBJECTIFS PRÉPARÉS À PARTIR DE COMPOSITIONS THERMOPLASTIQUES AYANT UNE PLASTICITÉ ÉLEVÉE ET UNE DUCTILITÉ ÉLEVÉE, ET PROCÉDÉ DE PRÉPARATION D'OBJECTIFS
Abstract:
(EN) Disclosed herein is a camera lens comprising a thermoplastic composition comprising a poly(aliphatic ester)-polycarbonate copolymer comprising soft block ester units derived from an alpha, omega C6-20 aliphatic dicarboxylic acid or derivative thereof, a dihydroxyaromatic compound, and a carbonate source, wherein the thermoplastic composition has a melt volume rate of 13 to 25 cc/10 min at 250 °C and under a load of 1.2 Kg and a dwell time of 6 minutes, according to ASTM D1238-04, and wherein the camera lens has an effective lens area of 0.5 to 100 mm2. A method of making the camera lens, and a camera lens comprising a thermoplastic composition comprising a redistribution product of a poly(aliphatic ester)-polycarbonate, are also disclosed.
(FR) L'invention porte sur un objectif comprenant une composition thermoplastique qui contient un copolymère de poly(ester aliphatique)-polycarbonate comprenant des unités ester de séquence molles issues d'un acide alpha, oméga dicarboxylique aliphatique en C6-20 ou d'un dérivé de celui-ci, un composé dihydroxyaromatique et une source de carbonate, la composition thermoplastique ayant un débit volumique à l'état fondu de 13 à 25 cm3/10 min à 250°C et sous une charge de 1,2 kg et un temps de séjour de 6 minutes, selon ASTM D1238-04, et l'objectif ayant une surface de lentille efficace de 0,5 à 100 mm2. L'invention porte également sur un procédé de fabrication de l'objectif, et sur un objectif comprenant une composition thermoplastique comprenant un produit de redistribution d'un poly(ester aliphatique)-polycarbonate.
