✦ Synopsis

Single crystals of pTS (bis-p-toluene sulphonate of ?,4-hesadiyne-1,6-dial), when anneAed at 350 I;, generate an rlcctrical signal peaking at a time corresponding to that of a maximum polymerization rate. It is shown that a steady-state polarization of the order of IO4 C/m* is built into th e pTS samples during the polymerization. The effect is probably associated with a non-compensated dipolar species created on polymerizing pTS crystals, and possibly also accounts for the pyroelectricity of poly-pTS.

To improve the blood compatibility of a segmented polyurethane (SPU), phospholipid polymer, i.e., 2-methacryloyloxyethyl phosphorylcholine (MPC) copolymerized with cyclohexyl methacrylate or 2-ethylhexyl methacrylate, was blended into SPU as a polymeric additive. The blending was achieved by a solve
