Abstract
Disclosed are a liquid-crystalline resin composition comprising (A) from 20 to 99 parts by weight of a liquid-crystalline resin and (B) from 1 to 80 parts by weight of aluminium borate whiskers of which the grain size distribution as obtained through laser diffractometry is such that D90/D10 is from 7.5 to 20, and precision moldings of the composition.
Claims20
A liquid-crystalline resin composition comprising (A) 100 parts by weight of a liquid-crystalline resin and (B) from 1 to 300 parts by weight of aluminum borate whiskers of which the grain size distribution as obtained through laser diffractometry satisfies the following requirement:
