摘要：
PROBLEM TO BE SOLVED: To provide a new transparent polymer product having improved stability to light, oxygen, heat and influence of offensive chemical substances and thin thickness and effective as selective UV filter for agricultural use and several new stabilizers suitable for the use. SOLUTION: This new transparent polyolefin, polyester or polyamide product has 1-500 μm thickness and is stabilized from light, oxygen, heat and/or influence of offensive chemical substances by adding hydroxyphenyltriazine UV absorber in an amount of 0.005-0.30 wt.% based on polyolefin, polyester or polyamide to a polymer base material. The transparent product stabilized thus is an agricultural film containing a sterically hindered amine as other stabilizer. The new product is effective as a selective UV filter, particularly useful for agriculture.
