摘要： The invention provides a dispenser form for substainedly releasing vapor of a sex pheromone compound of pest insects with an object to control the population of the insects. The invention dispenser is characterized by the features that: the capacity thereof is sufficiently large to contain at least 100 mg of the pheromone; the barrier wall thereof through which the pheromone permeates to be released from the outer surface is made of a polymeric material swellable with the pheromone in an equilibrium swelling of 2-6% by weight at 20.degree. C.; and the outer surface area S thereof given in mm.sup.2 is sufficient to give a ratio S/W, W being the amount of the pheromone contained therein given in mg, in the range from 4 to 11. The rate of pheromone emission from the dispenser is relatively constant at 0.6 mg/day or larger over a long period of time of, for example, 3 months or longer.

摘要： This invention provides a composite hollow fiber comprising a porous hollow fiber substrate and a coating layer formed on at least one of the outer surface and the inner surface of said substrate. The coating layer comprises a polymer having at least one of the structural units represented by the formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a lower alkyl group; R.sup.2, R.sup.3 and R.sup.4, which may be identical or different, represent a hydrogen atom, a monovalent hydrocarbon group having 1 to 8 carbon atoms or a monovalent silicon-containing organic group.This composite hollow fiber is excellent in gas permeability and gas separation performance and has high heat resistance, humidity resistance and mechanical strength.
