THEREOF
Field of the Invention
The present invention relates to a polymeric composition comprising an aliphatic polyketone processed with ferromagnetic nano-sized iron oxide particles, and a production method thereof.
Background of the Invention
Aliphatic polyketones obtained by alternating copolymerization of carbon monoxide and olefins are of considerable interest because they offer a unique set of physical and chemical properties which made them suitable candidates for use as engineering plastics. This class of polymers consists of (a) perfectly alternating copolymer of carbon monoxide and ethylene and (b) terpolymers in which propylene is substituted for ethylene in amounts up to 6 mol %. The said polymers are semi-crystalline materials with high melting points and excellent hydrolytic stability. On the other hand, when they are kept in the melt state for too long, they can undergo aldol condensation reactions which result in crosslinking and viscosity buildup. Therefore, it is necessary to use caution during melt processing of these materials.
Japanese Patent document no JP07-000776, an application known in the state of the art, discloses a production method for polymeric film having excellent heat resistance as well as pressure and chemical resistance. In this method, polyketone polymer is mixed with fine particles to make a polyketone porous film having slit like fine narrow pores. The polymer with 40-95 wt% is mixed with 60-5 wt% fine particles such as calcium carbonate and crosslinked silicone resin; and fine porous poyketone films are prepared by stretching the mixture.
European patent application, 0455265A2, gives a general state of the art on heating of olefinic polymers having carbon monoxide as co-monomer by high frequency alaectromagnetic radiatio, especially microwaves.
United States Patent document no US2009127253, an application known in the state of the art, discloses temperature-controlled induction heating of polymeric materials. Induction heating technologies are used for processes such as welding, forging, bonding or setting polymeric materials. Controlled-temperature induction heating is obtained by using ferromagnetic particles having a specific Curie temperature. In an induction field, the ferromagnetic particles heat up until they reach their Curie temperature. This invention intends to bond thermoplastic materials and thermoset composites by making use of these particles.

A further objective of the present invention is to realize a polymer composition which minimizes the degradation of the polymer by preventing the material within the polymer particles from melting, and a production method thereof.
Detailed Description of the Invention
The polymer composition and a production method thereof realized to fulfill the objective of the present invention is illustrated in the accompanying figure, in which;
Figure 1 is the view of the flowchart of the polymer composition and a production method thereof.
The components in the figures are each given a reference number and the numbers refer to the following.
"Polymer composition and a production method thereof (100) realized to fulfill the objective of the present invention comprises the steps of
preparing polymer powder (101),
- preparing mixture containing iron oxide (102),
adding the polymer powder into the mixture containing iron oxide (103), removing the solvent (104),
obtaining polyketone material the surface of which is coated with iron oxide (105),
- molding the material (106),
heating the molded material by induction heating (107),
solidifying the heated material (108).
In the inventive polymer composition production method (100), first the polymer powder is prepared by grinding (101). In the preferred embodiment of the invention, the polymer used is a polyketone, namely, poly(l-oxotrimethylene); and the said polyketone polymer is produced by perfectly alternating copolymerization of ethylene and carbon monoxide under high pressure using a palladium-based catalyst.
In the step of preparing the mixture containing iron oxide (102), ferromagnetic iron oxide particles are mixed with a solvent. In the preferred embodiment of the invention, ferro-magnetic iron powders are nano-sized. In one embodiment of the invention, the solvent is hydrocarbon based. In another embodiment of the present invention, the solvent is water.
The polymer powder, which is previously prepared, is then added to the said mixture (103). After the mixture containing polymer powder and iron oxide is stirred thoroughly, the solvent is evaporated (104).
After the solvent is removed (104), the polyketone material, the surface of which is coated with iron oxide, is obtained (105).
The said polymeric material is then molded using an isostatic press (106). After molding, a conductive network of iron oxide is formed around polymer particles.
After molding, the shaped article (e.g. rod or film) is heated through induction heating (107). In this method, the article is placed near an induction coil which generates a magnetic field. Upon induction heating, the ferromagnetic iron oxide on the surface of the polymer particle will heat up and eventually melt the outermost portion of the particle leading to fusion bonding of each polymer particle. By means of the said heating method the thermal degradation of the polymer is minimized.
Finally the resulting polymeric material is solidified by cooling (108). The said cooling process can be performed under isostatic press in order to prevent the generation of voids that may form as a result of the shrinkage of the material during cooling.
The solidified material can then be machined using lathe and the like to make semi-conductive, thermally conductive, heat and solvent resistant, magnetic field- responsive articles or films for electronics, medical or chemical industry.
Within the framework of these basic concepts, it is possible to develop a wide variety of embodiments of the inventive polymer composition and production method thereof (100). The invention cannot be limited to the examples described herein; it is essentially according to the claims.
