crystallinity

PHB has an unusually high degree of crystallinity due to the stereoregularity of the perfectly isotactic chains.

The photodimerization reaction of an anthracene moiety in the smectic phase proceeded quantitatively and regioselectively.

【文摘】[GRAPHICS] Thermotropic liquid crystallinity can be induced for an anthracene having a dendritic substituent.

Results show that PP-R and PP-B are crystallizable,but the crystallization rate and crystallinity of PP-R are slower and lower than that of PP-B.

结果表明,PP-R和PP-B都能结,但PP-R结较慢、结度较低;
