12 NOTICES [PYOC. SOC. Analyt. Chew. Notices FARADAY SOCIETY AN informal discussion on The Molecular Weight and Molecular-Weight Distribution of High Polymers will be held at Battersea College of Advanced Technology London S.W.11 on March 30th 1966. It is intended to discuss recent experimental methods for determining molecular weights and molecular-weight distributions of high polymers and the extent to which they can be used to provide information about the molecular state of polymers in solution. Offers of short contributions should be sent to and further details of the meeting can be obtained from Dr. P. Howard Chemistry Department Battersea College of Advanced Technology London S.W.ll.
