摘要:
A preparation comprising a medicinal solution filled in a transparent syringe tube or vessel molded from a resin composition comprising a phosphate represented by general formula (1) as a nucleating agent and a propylene polymer as a base material. The invention can provide a medicated preparation which is excellent in transparency and highly safe because the resin additive does not dissolve in the solution even when the solution is filled for long. The preparation is particularly useful as a medicated syringe preparation.

and poly(pentaerythryl diphosphonates) of formula (II):
are described. Flame-retardant compositions are also described, which include a thermoplastic polymer and a certain amount of self-extinguishing agent consisting of one of the above-mentioned pentaerythryl diphosphonates or poly(pentaerythryl diphosphonates).
摘要:
Die erfindungsgemäßen flammgeschützten, nicht tropfenden Polyalkylenterephthalat-Formmassen auf Basis von Phosphorsäureestern können verwendet werden zur Herstellung von Formkörpern. Durch den Zusatz der bestimmten Phosphorsäureester wird das Brandverhalten der Polyalkylenterephthalat-Formmassen verbessert, wobei insbesondere in Kombination mit hochwärmeformbeständigen Thermoplasten eine überraschende Reduzierung des Phosphorgehalts in den Formmassen erreicht wird.

A replication composition includes at least 45 weight percent (wt) of a polycarbonate; 3 to 55 wt% of a polyester comprising a poly(C1-6 alkylene) terephthalate or a polyester comprising repeating units of Formula I: (I); wherein each T is independently a C5-7 cycloaliphatic group or C6-12aromatic group, and each D is independently a C6-12 aromatic group or C2-12 aliphatic group, provided that at least 50 mole percent of D is a 1, 4-cyclohexanedimethyl group or a C2-12 aliphatic group; wherein the polyester has a melt viscosity between 0.01 and 3,000 poise (0.001 and 300 Pa∙s) measured at 1500/seconds shear rate, at a temperature of 275°C; and 0.01 to 4 wt% additives; wherein the weight percentages are based on 100 wt% of the composition.
摘要:
A polylactic acid resin composition containing a polylactic acid resin, glass fibers having an average aspect ratio (average fiber length/average fiber diameter) of 5 or more, and a metallic pigment, wherein the glass fibers are contained in an amount of from 2 to 35 parts by mass, and the metallic pigment is contained in an amount of from 0.1 to 8 parts by mass, based on 100 parts by mass of the polylactic acid resin. Since the polylactic acid resin composition of the present invention has excellent moldability, and is capable of providing a molded article with high designability, including a transparent surface layer and an inner layer with a lamellar texture in the nashiji patterns, the polylactic acid resin composition can be suitably used in various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts.
