A flexibilized resorcinolic novolak resin is prepared by reacting a phenolic compound, such as resorcinol, with an unsaturated dihydroxy, an unsaturated aldehyde, an aliphatic dialdehyde, or a mixture thereof. An aldehyde (different from the unsaturated aldehyde and the aliphatic dialdehyde) is either simultaneously or subsequently added to the reaction mixture. The flexibilized resorcinolic novolak resin can be used in an adhesive composition for enhancing the adhesion between tire cords and rubber for tire applications.
将间苯二酚等酚类化合物与不饱和二羟基、不饱和醛、脂肪族二甲醛或它们的混合物进行反应,可制备柔性间苯二酚酚醛树脂。醛(不同于不饱和醛和脂肪族二醛)同时或随后加入反应混合物中。柔性化的间苯二酚酚醛树脂可用于粘合剂组合物中,以增强轮胎应用中轮胎帘子线与橡胶之间的粘合力。
