Problems solved by technology

However, in order to achieve a considerable improvement in impact strength, the rubber content should be about 20% by weight or more at a temperature of -30°C or lower which significantly reduces the bending coefficient, resulting in a decrease in product hardness

Abstract

The present invention provides a polyketone composition having about 40-90 wt % of polyketone, about 5-40 wt % of polyamide, and about 5-20 wt % of modified rubber. The composition of the present invention greatly improves the impact resistance of polyketone, which has increased heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance or the like, and thus may be widely applied in various industrial fields, such as automotive parts including wheel covers, wheel caps, fuel filler necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gear, junction boxes, connectors, seat backs or the like, electric / electronic parts, and household items, thereby providing durability of the parts and price competition.

Description

technical field [0001] The present invention relates to polyketone compositions having improved impact resistance. Background technique [0002] Polyketones (PK) are terpolymers obtained by the polymerization of carbon monoxide, ethylene and propylene monomers. Compared to other engineering plastics such as polyamide, polyester, polycarbonate, etc., the price of these raw materials is quite low, and the cost of their polymerization process is relatively low. Polyketones also have excellent resistance to heat, chemicals, fuel permeation and abrasion. Thus, it can be applied to various industrial fields because of its impact resistance. [0003] Polyketone can be blended with polyamide 6 (PA6) to improve its impact resistance, however as described in Korean Patent No. 10-2010-0065526, its impact resistance is less effective in dry state. On the contrary, as described in Journal of Applied Polymer Science, Vol.116 (2010), pp 3056-3069, in a wet state, its impact resistance p...
