Polybutene-1 is an unusual polymer having high environment crackresistance,toughness, creepresistance,low glass transition temperature, flexibility etc. making it attractive for pipe and tubing applications. However, itexists in four polymorphic forms and has most peculiar solid-solid transformation taking place over long period of time (over days) which is the major drawback limiting its applications. There have been several efforts made in the pasttoaccelerate the process of crystal transformation from form-II to form-I whichismoststableofallthepolymorphs. Techniquessuch as mechanicalstretching, electron beamirradiation, additionof co-monomer, annealing etc. have been tried in the past [1-5] to obtain the stable form-I of polybutene-1 (PB1). In this paper, we describe the effect of addition of nano silica on the rate of transformation of form-II to form-I ofPB1.
