molecular weight of a polymer is of prime importance in its synthesis and rate constant can be expressed by an Arrhenius type relationship K = A eE/RT Where A is the collision frequency factor, E the Arrhenius activation energy, and T the Kelvin plot of lnK versus 1/T allows the determination of both E and A from the slope and intercept, a waterinsoluble or only slightly watersoluble monomer is added, a very small fraction dissolves and goes into large but still small portion of the m onomer enters the interior hydrocarbon part of the largest portion of the monomer is dispersed as monomer : There has been a rapidly increasing effort in the last ten to fifteen years toward the synthesis of new polymers with markedly higher temperature resistance than those previo usly catalysts usually must be prepared at the low temperatures since most of them bee heterogeneous when prepared at or warmed up to the temperatures above abou 、從句分詞不定式這些是寫作時常用且必須用到的結(jié)構(gòu)一定要掌握在學(xué)術(shù)論文中從句分詞不定式通常用來作修飾Applications in the relatively new field of tissue engineering, where polymers are used to assist regeneration of threedimensional tissue structures, are more and more int egrated with biological are three general synthetic approaches that have been used to produc e polymers with increased thermal certain symmetry requirements
