We report a wide angle neutron scattering experiment on atactic polystyrene, recently performed on the novel small angle neutron diffractometer for amorphous and liquid samples (SANDALS) commissioned at the pulsed neutron facility ISIS (UK). The use of SANDALS allows for the first time true quantitative neutron scattering data to be obtained over a large scattering vector range for hydrogenous polymers. Results for samples of both totally deuterated and totally protonated polystyrene are presented and compared with predictions from statistical models for the chain configuration. The possibility offered by SANDALS of investigating the local structure of hydrogenous polymers offers exciting prospects, particularly in the study of polymers of technological or commercial importance.
