The second part includes the synthesis and characterization of the acrylated unsaturated polyester and the kinetic studies on the Ar-UPE/ triethylene divinyl ether (DVE-3) photocuring system, the rheology and properties of film after photocuring. The third part includes the synthesis and characterization of the urethane modified unsaturated polyester and the kinetic studies on the PU-UPE/DVE-3 photocuring system, the rheology and properties of film after photocuring. The fourth part includes the synthesis and characterization of the vinyl ether end capped polyurethane and the kinetic studies on the VE-PU/DVE3 photocuring system, the rheology and properties of film after photocuring.

The cation dyeable polyester fiber,which was developed by Do punt corporation in 1958 and commercialized in 1962 known as Dacron,is a main representative of new polyester fibers because of excellent dyeability and low cost.

阳离子可染聚酯纤维首先由美国杜邦公司于1958年研制成功，并于1962年实现商品化，商品名为达克纶，由于其优异的染色性能和低廉的染色成本，使它成为聚酯纤维新品种的主要代表。

Polyester fibers are white and can vary from luster and semi-translucent to dull and opaque depending on the amount of the lustrant added to the polymer.

聚酯纤维呈白色，它可以是有光泽的、半透明的。聚酯纤维的光泽取决于所加入光泽剂的量。

Polyester fibers are white and can vary from luster and semi-tranalucent to dull and opaque depending on the amount of the lustrant added to the polymer.

聚酯纤维呈白色，它可以是有光泽的、半透明的、无光泽或不透明的。聚酯纤维的光泽取决于所加入光泽剂的量。

A series of maleopimaric acid polyester amino resins were made from maleo￣pimaric acid polyesters crosslinked by etherified melamine formaldehyde resins.

以马来海松酸和线性小分子二醇为原料，合成马来海松酸聚酯多元醇，再用氨基树脂交联，制备马来海松酸聚酯氨基树脂。

Also this year, the company has introduced its Louis Bernard Bonus Passus Cote du Rhone in PET bottles, a first for a wine produced under France's appellation d'origine controlee system, which is designed to guarantee quality.

也就在今年，Louis Bernard的Bonus Passus Cote du Rhone已经采用了聚酯酒瓶的技术，这是第一款在美国出售的具有聚酯瓶装的AOC级法国葡萄酒。

Data reveal that the composite polymer network of unsaturated polyesterlpolyesterurethane(r = NCO/OH = 0.4) is superior to its counterparts from polyetherurethane or polymethylene polyphenyl isocyanate, PAPI in mechanical properties.

数据揭示了不饱和聚酯／聚附聚氨酯CPN，当r＝NCO／OH＝0.4时，它的物理力学性能优于不饱和聚酯／聚醚聚氨酯CPN或HUP／PAPICPN组成物。

The practice showed that the new theory can describ and predict the mechanical relaxations of PET/PHB copolyesters successfully, and previde the useful imformation for the structure analysis of the copolyester as well.

实践表明，新的唯象理论不但能成功地描述和估算PET/PHB共聚酯的力学松弛行为，还能为共聚酯的结构分析提供有用的信息。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
