    • Process for preparation of 2-anthryl and substituted 2-anthryl functional monomers and polymers. In the process for preparation of these monomers, an anthracenic reactant of the formula: ##STR1## wherein X and Y are independently selected from hydrogen, chlorine, bromine, alkyl of 1 to 4 carbon atoms or phenylIs acylated in nitrobenzene under conditions which favor reaction at the two position. The resulting acylated product can then be (a) reacted with an alkylidenephosphorane (Wittig synthesis) or (b) reduced to the corresponding alcohol. Subsequent to such reduction, this alcohol can undergo further modification at the hydroxyl function to form a polymerizable addition monomer. Through the proper selection of the relative concentration of reactants and control over processing conditions, it is possible not only to prepare such monomers in high yields but also upon polymerization of such monomers, to obtain high molecular weight 2-anthryl and substituted 2-anthryl functional polymers (molecular weight of at least 10.sup.4). Polymers of such high molecular weight can readily be formed without the use of binders into self-supporting films. Such films are intrinsically photoconductive in the ultraviolet region of the electromagnetic spectrum and have good transport capabilities for charge carriers of both polarities.
    • 制备2-蒽基和取代的2-蒽基官能单体和聚合物的方法。 在制备这些单体的方法中,下式的蒽反应物:其中X和Y独立地选自氢,氯,溴,1至4个碳原子的烷基或苯基。在氮气条件下,在氮气下进行酰化。 在两个位置的反应。 所得到的酰化产物可以(a)与亚烷基次磷酰(Wittig合成)或(b)还原成相应的醇反应。 在这种还原之后,该醇可以在羟基官能团进一步改性以形成可聚合的加成单体。 通过适当选择反应物的相对浓度并控制加工条件,不仅可以以高产率制备这些单体,而且可以在这些单体聚合时获得高分子量2-蒽基和取代的2-蒽基官能团 聚合物(分子量至少为104)。 可以容易地形成这样高分子量的聚合物,而不需要使用粘合剂作为自支撑膜。 这样的膜在电磁光谱的紫外区域是本征光电导,并且对于两极性的电荷载体具有良好的传输能力。

    • Method for achieving free radical initiated copolymerization of an addition monomer having pendant therefrom a strong donor group with an addition monomer having pendant therefrom a strong acceptor group. Copolymers prepared according to this method can be represented by the following formula: ##STR1## wherein R is hydrogen or methyl;R' is hydrogen or methyl;R" is hydrogen or methyl;R'" is selected from the group consisting of --NO.sub.2, halogen, --CN and --CF.sub.3 ;X and Y are independently selected from the group consisting of hydrogen, chlorine, bromine, alkyl of 1-4 carbon atoms and phenyl;a and b can range from 0-4; andn and m can range from about 5 to about 95 percent.The polymeric compositions prepared according to this method are suitable for use in electrophotography either alone as the primary photoresponsive entity or in combination with other photoconductive materials.
