摘要： An isocyanate-terminated prepolymer having three components. The first component is 30-60 wt % polymerized residues of a first polyol containing a substituent of formula (I) attached via a carbon-carbon single bond to a saturated carbon atom in a fatty acid hydrocarbyl group; wherein R1 and R2 are esterified residues of aliphatic or cycloaliphatic diols; and wherein the first polyol contains: (i) from 0.33 to 0.4 units of formula (I) per fatty acid hydrocarbyl group, and (ii) from 0 to 12 wt % esterified residues of at least one C4-C12 anhydride, C4-C12 diacid or C4-C12 lactone, not including units of formula (I) attached to a fatty acid hydrocarbyl group; and wherein the first polyol has a hydroxyl number from 75 to 150 mg KOH/g. The second component is 40-55 wt % polymerized residues of diphenyl methane diisocyanate. The third component is 0-20 wt % polymerized residues of a glycol having Mn from 300 to 3500.
摘要翻译： 具有三种成分的异氰酸酯封端的预聚物。 第一组分是含有通过碳 - 碳单键与脂肪酸烃基中的饱和碳原子连接的式（I）的取代基的第一多元醇的30-60重量％聚合残基; 其中R1和R2是脂族或脂环族二醇的酯化残基; 并且其中所述第一多元醇包含：（i）每个脂肪酸烃基为0.33至0.4单位的式（I）单元，和（ii）至少一种C 4 -C 12酐，C 4 -C 12烷基酯的0-12重量％酯化残基 二酸或C 4 -C 12内酯，不包括连接到脂肪酸烃基的式（I）单元; 并且其中所述第一多元醇具有75至150mg KOH / g的羟值。 第二组分是二苯基甲烷二异氰酸酯的40-55重量％聚合残余物。 第三成分是Mn为300〜3500的二醇的聚合残渣为0〜20重量％。
