- the present invention relates to a composition based on amorphous transparent polyamide or very low crystallinity, and copolyamide with ether units and amide units.
- Transparent amorphous polyamides or those which are very slightly crystalline, that is to say whose enthalpy of fusion during the second heating of an ISO DSC (delta Hm (2)) is at most equal to 30 J / g, even 10J / g (in the case of the "Trogamid CX7323" cited below), are materials which have the following advantages: high transparency, very good thermomechanical behavior (high deflection temperature under load (HDT) due to the glass transition temperature (Tg) high and above 90 ° C), held fairly good shock, chemical resistance and stress cracking resistance "stress cracking" good and superior to other common amorphous transparent polymers, such as polycarbonate, polystyrene, polymethylmethacrylate.
- HDT high deflection temperature under load
- Tg glass transition temperature
- amPA TR amorphous or very slightly crystalline transparent polyamides
- amPA TR amorphous or very slightly crystalline transparent polyamides
- IPD isophoronediamine
- amorphous or very slightly crystalline transparent polyamides have the following drawbacks: rather difficult injectability because of their high viscosity (if they are chosen as fluids, then their mechanical properties, in particular in impact, are reduced, as well as their holding properties chemical); medium impact strength, especially in comparison with polycarbonate or non-transparent semi-crystalline polyamides, especially if these are modified shock; rigidity often too high; - alternating fatigue strength ("ross-flex" ASTM1052); chemical behavior significantly lower than that of semi-crystalline polyamides; and medium UV resistance, especially in the absence of stabilizer (the addition of compounding stabilizer resulting in yellowing of the polymer or the formation of black spots, which is often too detrimental to its use in applications where aesthetics is important as for example glasses frames).
- a well-known improvement route is to mix the amorphous transparent polyamide with a minor amount of semi-crystalline polyamide (typically non-transparent).
- the European patents EP 550 308 and EP 725 101 describe alloys of transparent amorphous polyamide combined with a non-transparent semicrystalline polyamide, all giving a transparent and amorphous or substantially amorphous material, that is to say of which the enthalpy of fusion is less than 30 J / g, even 10J / g, and no real mechanical strength above its Tg and before its Tm (melting temperature).
