<p>1,242,459. Elastomeric particle containing laminate. GENERAL TIRE & RUBBER CO. 8 Oct., 1969 [11 Oct., 1968], No. 49363/69. Heading B5N. A laminate comprises layers of a thermosetting resin compound wherein alternate layers and the outermost layers contain a uniform physical dispersion of elastomeric particles. The thermosetting resin layers may contain a fibre reinforcement, e.g. glass fibres. The preferred thermosetting resins are polyesters, and many elastomeric materials are specified. The amount of elastomeric material present may vary between 2 to 20 parts per 100 parts of thermosetting resin. The laminate is stated to possess a high reverse impact strength.</p> |
