(1) wherein R1 and R2 are the same or different and represents H, C1-C6 alkyl or C6-C18 aryl, M is Al, m is 3, B: calcium metal element, wherein the metal weight content of calcium element in the total additive is 10-600 ppm.
2. The method according to claim 1 for the polymer additive, wherein the weight content of the calcium metal element in the total additive is 50-500 ppm, preferable weight content is 100-400 ppm, more preferably the content is 150-300 ppm by weight.
3. The method according to claim 1 or 2, a kind of additive for polymer, wherein the testing method of the weight content of metal calcium element, taking 0.05 + 0.005g additive sample for the polymer, accurate to 0.001 g, putting into microwave digestion tank, then adding 10 mL ketopantoate to microwave digestion pot to make it completely immersing the sample, slowly dropping 1-2 mL hydrogen peroxide, reacting the sample with digesting acid 1-2 min, cover upper cover sealing digestion tank; in the 220 °C blast oven to digestion, the digestion time is 2h, after finishing the digestion, taking out the digestion pot, cooling to room temperature, measuring, if still some particles not digesting, then slowly dropping 1-2 mL hydrogen peroxide repeating said digesting step, to be measured; if the secondary is not digested completely, the digestion liquid after clarifying solution is obtained by filtering the sample to be tested, specifically, the microwave digestion solution in the tank by 0.45 microns of filtering film is transferred to a volumetric flask, proper distilled water for many times washing microwave digestion tank and the washing liquid is transferred to the volumetric flask, and then diluted to 50 ml. with distilled water, shaking evenly, measuring, full automatic inductive coupling plasma atomic emitting spectrograph analyzing with Agilent Company of 720ES weight content of metal calcium element in the sample to be detected, taking three testing value of the average as a final result.
4. The method according to claim 1 said the one kind of additive for polymer, wherein R1, R2 represents ethyl, propyl, butyl, hexyl, or cyclohexyl.
5. The method according to claim 1 for the polymer additive, wherein the calcium metal elements from a calcium-containing compound, the calcium-containing compound is selected from calcium oxide, calcium carbonate, calcium sulphate crystal whisker, calcium stearate or montanic acid calcium in the one kind of or several.
