Definitions
- TPEs exhibit cold flow resistance and resiliency that generally exceeds that of TPOs. This cold flow resistance and resiliency enables TPEs to be used in applications where the relatively poor cold flow and resiliency of polyolefins such as polypropylene unacceptable.
- Such applications include molded articles for automobiles and appliances. In molded articles, shape is often a critical parameter. Cold flow due to a contained load or due to an applied force could cause unacceptable non-recoverable deformation in a molded part. Additionally, much less weight and time would be necessary to cause a load-set or deformation due to a static load if the molded parts are fabricated from most polyolefins rather than TPOs. Versus TPEs, the performance of most polyolefins would be even poorer.
- the polymers ofthe present invention are substantially isotactic in nature.
- the polymers will generally have a narrow molecular weight distribution, as characterized by the M ⁇ /M,,, (weight average molecular weight/number average molecular weight) (molecular weight distribution MWD), of ⁇ 5.
- M ⁇ /M, (MWD) is determined by Gel Permeation Chromatography (GPC), as is molecular weight.
- GPC Gel Permeation Chromatography
- Tubing may be obtained by profile extrusion.
- the tubing will generally be in the range of from about 0.31 cm (1/8") to about 2.54 cm (1 ") in outside diameter, and have a wall thickness of in the range of from about 254 ⁇ m (10 mils) to 0.5 cm (200 mils).
- Molded articles may be made by any techniques known to those of ordinary skill in the art. For example, molded articles may be fabricated by injection molding, blow molding, extrusion blow molding, rotational molding, and foam molding. Molded parts are found in many thicknesses of 500 ⁇ m (20 mils) or greater. For molded articles, the thickness of a cross section ofthe article will generally be in the range of from about 508 ⁇ m to about 2.5 cm.
- Molded articles for health care devices such as, for example, syringes are also contemplated.
- Table I sets forth the physical property data for a propylene-ethylene copolymer film and a propylene-hexene copolymer film meeting the description of this application. The film test is used as an indicator of molded article or extruded profile performance.
- the data in Table I show that other physical/mechanical properties of articles fabricated from the resins ofthe present invention will also show an improvement in value, as noted before, when compared to propylene copolymers of lower alpha-olefins.
- propylene-HAO copolymers exhibit other improved physical properties.
- Table I compares physical properties of propylene copolymers of ethylene and propylene copolymers of
- Example 2 To the autoclave ofExample 2, 550 grams of propylene is added along with approximately 45 grams of 1-octene as the molar amount ofExample 3. The catalyst ofExample 1 is added and the temperature is controlled as in Example 2.
- a film ofthe copolymer to be characterized is formed by compression molding 9.2 grams ofthe granular copolymer between Mylar® sheets in a form 15 x 15 centimeters in area and 0.5 mm in thickness.
- the molding procedure is: 1) close the platens (controlled at a temperature of 200° C) until they contact the sample; hold for one minute with no applied pressure; 2) increase the clamping force to 10 Tons and hold for one minute; 3) increase the clamping force to 40 tons and hold for two minutes; 4) release the clamping force and quench the film (still between the Mylar sheets) in a water bath at room temperature. After the films are conditioned for six days at room temperature, dumbbell samples are die-cut from the films.
- the tensile properties ofthe resulting samples are measured on a Zwick REL 2051 tensile tester at a temperature of 25 ⁇ 2 degrees C for the standard tensile properties, procedure DIN 53457 (1987) is adhered to.
- the tensile specimen is loaded into the tester just as if one are doing the standard tensile test.
- a predetermined load is applied and the specimen elongation is recorded as a function of time.
- the load is chosen to be in the range of 50-60% of that which would cause the specimens to experience yielding (for samples presented here, a load of 11.7 MPa is chosen).

Abstract
Un article moulé ou extrudé, réalisé en un copolymère de propylène et d'une α-oléfine supérieure (c'est-à-dire ayant 5 atomes de carbone ou davantage) obtenu en utilisant un système catalyseur du type alliage organométallique offre une bien meilleure résistance au fluage à froid et une bien plus grande résilience que lorsque ce copolymère de propylène contient une α-oléfine ayant 4 atomes de carbone ou moins. D'autres caractéristiques telles que la résistance à la rupture et la résistance aux impacts sont aussi nettement plus élevées. Ces polymères peuvent être utilisés d'une manière avantageuse pour réaliser des profilés extrudés et des pièces moulées soit seuls, soit dans une oléfine thermoplastique. Les pièces réalisées en copolymères de propylène et d'une α-oléfine supérieure ont une résistance améliorée au fluage par comparaison avec les copolymères de propylène et d'éthylène.
