The crystallization and melting behavior of mellocene - catalized branched and linear polyethylenes of low molecular weight was studied. it was found that the crystalline lattice of branched polyethylene is larger than that of linear polyethylene because of the existence of branched chains. the melting behavior of branched polyethylene is similar to that of linear polyethylene since the branched chains can not enter the lattice. however, the crystalline behavior of low molecular weight branched polyethylene is the same as that of high molecular weight linear polyethylene, but different with that of low molecular weigh linear polyethylene. kinetics theory analysis evidenced that the transition temperature of growth regime of the branched polyethylene is about 20 lower than that of linear polyethylene with the same molecular weight. it may be attributed to the existence of short branched chains
研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為，發現支化聚乙烯的結構與線性聚乙烯相同為正交結構，但晶格略有膨脹.支鏈的存在對熔融行為影響不大，兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加，表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響，主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程，使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明，低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20 -

For the crystalline polymer matrix, the ptc transition temperature is close to the melting point, while for the amorphous polymer matrix, the ptc transition temperature is close to the glass transition temperature
Ptc轉變溫度與體積膨脹的轉變溫度非常一致，對于結晶聚合物基體體系， ptc轉變溫度在基體的熔點附近，而對于非晶聚合物基體體系， ptc轉變溫度在基體的玻璃化轉變溫度附近。 -
The research on the effect of liquid - liquid transition of polyacrylate on crystallization - melting of pdms indicates that above the melting temperature of pdms, pdms is reinforced by a special mutual action between p - electron in carbonyl of polyacrylate and 3d orbit in si atom of pdms, while below the temperature, the pdms crystal is lessened, which can not completely remove the crystal of pdms. however, it is the crystallization behavior of pdms that results in its most segments relaxation being restrained
研究聚丙烯酸酯液一液轉變對聚二甲基硅氧烷結晶一熔融影響的結果表明：碳基碳原子上p電子與出原於中3d軌道相互作用，在聚h甲基硅氧烷熔融轉變溫度以上，對其有分子增強作用；在聚二甲基硅氧烷熔融轉變溫度以下，霎對其有降低結晶度的作用，但不能消除結晶現象。 -
On the base of tg - dta, found the yb : kgw crystal has very good thermal stability under 1100, which has two obvious absorption peak at 1088 and 1025, contrast with the pure kgw crystal ( melting point at 1005, phase transition temperature from tetragonal system to monoclinic is 1075 ), we know the yb : kgw crystal ' s melting point is the absorption peak at 1088, phase transition peak from tetragonal system to monoclinic is the absorption peak at 1025
利用tg - dta對所生長的yb ： kgw晶體測定說明，其在1100以下的熱穩定性是很好的。 yb ： kgw晶體在1088和1025有兩個明顯的吸收峰，判斷在1088處較寬的吸收峰是yb ： kgw晶體的熔點， 1025處的吸收峰是yb ： kgw晶體從四方晶系向單斜晶系的相轉變峰。
