摘要： Various fluoropolymers have been proposed for imparting oil and water repellency to leather. Commonly, these fluoropolymers are amphiphilic; i.e., they are made from at least one monomer which is hydrophobic and at least one monomer which is hydrophilic. The present invention identifies and remedies disadvantages associated with the ability of amphiphilic fluoropolymers to impart oil and water repellency to leather. Contrary to conventional thinking, it has now been discovered that the incorporation of hydrophilic groups in a fluoropolymer undesirably reduces its ability to impart water resistance to leather. Correspondingly, it has also been discovered that a fluoropolymer incorporating fewer or no hydrophilic groups imparts superior oil and water repellency to leather when compared to fluoropolymers incorporating more hydrophilic groups. Therefore, this invention provides fluoropolymers which incorporate reduced levels of hydrophilic groups.

摘要： 피혁에발유성및 발수성을부여하기위한다양한플루오로중합체가제안되어있다. 일반적으로, 이러한플루오로중합체는양친매성이며; 즉적어도하나의소수성단량체와적어도하나의친수성단량체로부터제조된다. 본발명은양친매성플루오로중합체가피혁에발유성및 발수성을부여하는능력과관련된불리한점을확인하며이를해결한다. 종래의생각과는대조적으로, 플루오로중합체중에친수성기를포함하는것이피혁에내수성을부여하는그의능력을바람직하지않게감소시킨다는것을이제알아내었다. 상응하여, 또한친수성기를더 적게또는전혀포함하지않은플루오로중합체는, 더많은친수성기를포함하는플루오로중합체와비교할때, 피혁에더 우수한발유성및 발수성을부여한다는것을알아내었다. 따라서, 본발명은감소된수준의친수성기를포함하는플루오로중합체를제공한다.
