    • A hydrophobic polymer made by incorporating alkyl chains pendant to the main backbone of the polymer which allows creating polymers with alkyl chains pendant to the polymer chain. Synthetic and naturally derived starting materials such as tallow diamine or ethoxylated tallow amine typically contain a mixture of chain lengths with varying degrees of branching and unsaturation. The unsaturated positions in the final polymer can be made to cross-link in the presence of a catalyst to increase the hardness and reduce the effect of heat and solvent borne exposures. The present invention can be a replacement to current monomers or additive to common polymers to replace or modify the current polymers to alter the properties of a polymer adding the known benefits of fatty compounds to common polymers such as hydrophobicity, or in altering the HLB (hydrophilic lipophilic balance) of polymeric surfactants.
    • 通过将烷基链引入到聚合物的主骨架上制成的疏水性聚合物,其允许产生具有垂直于聚合物链的烷基链的聚合物。 合成和天然衍生的起始物质如牛脂二胺或乙氧基化牛脂胺通常含有具有不同支化度和不饱和度的链长度的混合物。 最终聚合物中的不饱和位置可以在催化剂存在下进行交联以增加硬度并降低热和溶剂承受的影响。 本发明可以替代现有的单体或添加剂以代替或改性目前的聚合物以改变聚合物的性质,从而加入脂肪族化合物对普通聚合物如疏水性的已知益处,或改变HLB(亲水性 亲油平衡)的聚合物表面活性剂。
