Title: Reusable PVC obtd. from polymer wastes - by mixing with plasticiser and heating
IPC: C08J11/06
Filed: 1977-05-13
Abstract: Reusable PVC or copolymers vinyl chloride are obtd. from wastes of these materials by finely grinding the waste, mixing it with >=1 plastiser, and possibly also with >=1 lubricant or other classical constits. for PVC plastics, dividing it into sheets and heating it to a temp. equal to or below normal gelatinising temp. Method is used to give materials workable by dry-blending. It is iesp useful for rigid PVC, but is also applicable to supple or semi-supple blends. PVC waste in the vitrified state does not normally absorb plasticisers. The process overcomes the problem; if used on a large scale it would help to reduce extent of pollution by plastic materials.
