Polyol esters materials, which have been developed from ethylene glycol, glycerol, pentaerythritol and sorbitol with rosin, were investigated for their formed films and coating properties. Films were dried and characterized for chemical and mechanical resistances. Their films were highly resistant to water, solvents (acetone, toluene and methanol), and acids (10% hydrochloric acid and 20% sulfuric acid) and poorly resistant to alkali (10% sodium hydroxide) as well as adhesion, tensile strength, elongation test, modulus of elasticity, pinhole test and scratching and flexibility tests. Incorporation of ethylene glycol, glycerol, pentaerythritol and sorbitol with rosin was done to achieve good mechanical characteristics and high chemical resistance to these films. The prepared compounds were tested for antibacterial activity against Trametes versicolor and Gloeophyllum trabeum.

研究了由乙二醇，甘油，季戊四醇和山梨醇与松香开发而成的多元醇酯材料的成膜性和涂层性能。将膜干燥并表征耐化学性和机械性。他们的薄膜对水，溶剂（丙酮，甲苯和甲醇）和酸（10％盐酸和20％硫酸）具有很高的抵抗力，而对碱（10％氢氧化钠）以及粘附性，拉伸强度和伸长率的抵抗性很差测试，弹性模量，针孔测试以及刮擦和柔韧性测试。进行了乙二醇，甘油，季戊四醇和山梨糖醇与松香的掺混，以实现对这些薄膜的良好机械特性和高耐化学性。测试了所制备的化合物的抗细菌活性杂色的Trametes和Gloeophyllum trabeum。
