COPOLYMERIZATION OF DIETHYNYLBENZENE WITH 4,4'-DIPROPARGYL DIPHENYLETHER AND COPOLYMER PROPERTIES

Abstract

Abstract:

Copolymers,modified Polyarylacetylene (MPAA),of diethynylbenzene with 4,4'-dipropargyl diphe- nylether were prepared.The rheological and cure behavior of MPAA was investigated by using viscometer and DSC method respectively.The results revealed that MPAA showed excellent processability and offered lower cure exother- mic heat than PAA' s.Dynamic mechanical analysis (DMA) indicated that the cured MPAA resin showed good heat resistance with a glass transition temperature of over 340℃,and thermogravimetric analysis (TGA) indicated cured MPAA resins held high thermal stability.The glass fabrics reinforced MPAA composites were prepared and their properties were tested,the MPAA composites exhibited improved mechanical properties.

Key words: modified polyarylacetylene, 4, 4’-dipropargyl diphenylether, thermoset resin, composites
