A polyurethane radical composite material ( pu / p ( vc - vac ) ) was synthesized by reaction of hydroxyl vinyl chloride - acetate copolymer ( p ( vc - vac ) ) and pu 摘要试验研究了以羟基化的氯乙烯醋酸乙烯酯树脂为改性剂，与聚氨酯预聚体反应合成聚氨酯基氯醋树脂聚氨酯复合材料。
Several kinds of fillers , i . e . , phenol - formaldehyde , alkyd , polyester , polyurethane and poly - vinyl - acetate , were tried to coat surface of wheat straw board ( wsb ) in this paper 摘要对麦?人造板表面分别试验了酚醛树脂、醇酸树脂、聚酯树脂、聚氨酯、聚醋酸乙烯酯腻子，涂刮腻子后再喷涂丙烯酸漆，并测定漆膜附著力。
For poly ( vinyl acetate ) based lpas , it seemed that lpas with higher molecular weights worked better than that with the lower molecular weights and lpa with low molecular weights need high concentration for good shrinkage control 对于聚苯乙烯类的lpa - c ，试样收缩控制效果随着lpa - c浓度的增加而增强；对于聚醋酸乙烯酯类的lpa ，分子量较高的lpa比分子量较低的lpa的收缩控制效果好；分子量较低的lpa若要达到较好的收缩控制效果则需要较高的浓度。
In the volume change study , we found appropriate temperature is helpful for shrinkage control , and different lpas have different shrinkage control effects due to their dipole moment , tg , miscibility with upr and morphology after blending . there existed an optimal concentration range of poly ( vinyl acetate ) based lpas for shrinkage control . lpa was effective for shrinkage compensation in this range , on the other hand , lpa only acted as filler and the low profile effect vanished out of this range , however , for polystyrene based lpa , the more concentration the better shrinkage control 在膨胀研究中，发现适当的温度条件更有利于upr达到好的收缩控制效果；不同类型的lpa随着偶极矩、玻璃化温度、与upr的相容性、与upr的混合形态的不同，表现出不同的收缩控制效果；聚醋酸乙烯酯类的lpa - a存在一个最佳收缩控制的浓度范围，在这个范围之内， lpa起到补偿收缩的作用；而在这个范围之外， lpa的作用仅相当于填料，不能起到收缩控制。
The resting cells reaction experiment showed that it could also degrade other acetic ester compounds including ethyl acetate , vinyl acetate , chloroethyl acetate , propyl acetate , isopropyl acetate , butyl acetate , sec - butyl acetate and 1 , 3 - butanediol diacetate by producing aetate 休眠细胞反应试验表明，这株菌除降解醋酸异丁酯以外，还可降解醋酸乙酯、醋酸乙烯酯、醋酸氯乙酯、醋酸丙酯、醋酸异丙酯、醋酸丁酯、醋酸仲丁酯、醋酸丁二醇等醋酸酯类化合物及聚醋酸乙烯酯。
A detailed study of the morphology of low - profile unsaturated polyester resins after cure at low - medium temperature was carried out . the experimental results show that the influence of temperature on morphology of cured sample was smal 1 for poly ( vinyl acetate ) based lpas but large for polystyrene based lpa 文章详细研究了低轮廓不饱和聚酯树脂中低温下固化试样的形态，实验结果表明：温度对加入聚醋酸乙烯酯类lpa试样的固化形态影响不大，而对加入聚苯乙烯类lpa试样的固化形态则有较大的影响。
