  1. 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

    摘要對麥?人造板表面分別試驗了酚醛樹脂、醇酸樹脂、聚酯樹脂、聚氨酯、聚醋酸乙烯酯膩子，塗刮膩子后再噴塗丙烯酸漆，並測定漆膜附著力。
  2. For the sample with poly ( vinyl acetate ) based lpas, the morphology exists two transition points with the increase of lpa concentration

    對于含聚醋酸乙烯酯類lpa的試樣，形態隨著加入濃度的增加存在兩次明顯的轉變。
  3. 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

    在膨脹研究中，發現適當的溫度條件更有利於upr達到好的收縮控制效果；不同類型的lpa隨著偶極矩、玻璃化溫度、與upr的相容性、與upr的混合形態的不同，表現出不同的收縮控制效果；聚醋酸乙烯酯類的lpa - a存在一個最佳收縮控制的濃度范圍，在這個范圍之內， lpa起到補償收縮的作用；而在這個范圍之外， lpa的作用僅相當于填料，不能起到收縮控制。
  4. The preliminary study on alcoholysis of poly vinyl chloride - co - vinyl acetate

    氯醋樹脂醇解反應的初步研究
  5. Synthetic of poly vinyl acetate emulsion used for preventing spontaneous combustion of coal and study on behaviour of it

    防治煤層自燃的聚乙酸乙烯酯乳液的合成及其性能研究
  6. 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

    對于聚苯乙烯類的lpa - c ，試樣收縮控制效果隨著lpa - c濃度的增加而增強；對于聚醋酸乙烯酯類的lpa ，分子量較高的lpa比分子量較低的lpa的收縮控制效果好；分子量較低的lpa若要達到較好的收縮控制效果則需要較高的濃度。
  7. 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

    文章詳細研究了低輪廓不飽和聚酯樹脂中低溫下固化試樣的形態，實驗結果表明：溫度對加入聚醋酸乙烯酯類lpa試樣的固化形態影響不大，而對加入聚苯乙烯類lpa試樣的固化形態則有較大的影響。
