A marked gradient in surface pressure develops in monolayers of poly(vinyl stearate) (PVS) during compression. The gradient varies with position along the trough: it is large in the region close to the compression barrier and also near the other end of the trough, but relatively small at intermediat

Abstract
Homopolymerisation of vinyl stearate and its copolymerisation with five other fatty vinyl monomers have been carried out in benzene using benzoyl peroxide as the initiator. The comonomers included stearyl acrylate, stearyl methacrylate, allyl stearate, stearyl vinyl ether and divinyl sebacate. Stearyl acrylate and stearyl methacrylate furnished copolymers with inherent viscosities much higher than that of the vinyl stearate homopolymer while allyl stearate and stearyl vinyl ether gave copolymers with inherent viscosities much lower than that of the vinyl stearate homopolymer.

## Abstract The kinetics of copolymerisation of vinyl chloride with allyl chloride in chlorobenzene and in dichloroethane solvent have been studied by a dilatometric method. The compositon of the copolymers was determined by reduction with tributyltin hydride followed by infrared examination. Molec
