Abstract

Rigid or semi-rigid mouldings are manufactured from a paste of polyvinyl chloride dispersed in a plasticising agent comprising liquids of low volatility which are non-solvents for the polymer at room temperature, but rapidly dissolve it at elevated temperatures. The paste is intimately mixed with one or more easily polymerizable monomeric organic liquids having ethylenic unsaturation which are soluble in the plasticiser used for dispersing the polyvinyl chloride and which polymerize to give rigid products. The mixture is then moulded under such conditions of temperature, pressure and time as cause complete gelatinisation of the paste and complete polymerization of the monomer. If desired, a polymerization catalyst, e.g. benzoyl peroxide, may be added prior to moulding. Specified plasticisers are tricresyl phosphate, dicetyl phthalate and di-(ethyl hexyl) phthalate. Methyl methacrylate is the preferred monomeric liquid, and generally the monomer does not exceed 50 per cent of the weight of the paste. Specification 574,804 is referred to.
