Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
64 words
A LATEX CONTAINING DISPERSED INDIVIDUAL PARTICLES WHICH COMPRISE AGGLOMERATED BUTADIENE HYDROCARBON POLYMER HAVING ENTRAPPED THEREIN INDIVIDUAL PARTICLES OF INORGANIC REINFORCING PIGMENT WHICH AGGLOMERATED PARTICLES ARE FORMED BY THE COALESCENCE OF DISPERED BUTADIENE HYDROCARBON POLYMER PARTICLES AND THE ENTRAPMENT OF INDIVIDUAL PARTICLES OF REINFORCING PIGMENT BY THE COALESCING BUTADIENE HYDROCARBON POLYMER PARTICLES AS THEY COALESCE TO FORM A NEW LARGER DISPERSED BUTADIENE HYDROCARBON POLYMER PARTICLES.
Claim 2
Dependent Claim
64 words
A LATEX CONTAINING DISPERSED INDIVIDUAL PARTICLES WHICH COMPRISE AGGLOMERATED BUTADIENE HYDROCARBON POLYMER HAVING ENTRAPPED THEREIN INDIVIDUAL PARTICLES OF INORGANIC REINFORCING PIGMENT WHICH AGGLOMERATED PARTICLES ARE FORMED BY THE COALESCENCE OF DISPERED BUTADIENE HYDROCARBON POLYMER PARTICLES AND THE ENTRAPMENT OF INDIVIDUAL PARTICLES OF REINFORCING PIGMENT BY THE COALESCING BUTADIENE HYDROCARBON POLYMER PARTICLES AS THEY COALESCE TO FORM A NEW LARGER DISPERSED BUTADIENE HYDROCARBON POLYMER PARTICLES.
Claim 3
Independent Claim
106 words
A METHOD FOR INTERNALLY REINFORCING BUTADIENE HYDROCARBON POLYMER PARTICLES OF AN EMULSION-POLYMERIZED BUTADIENE HYDDROCARBON POLYMER SYNTHETIC LATEX IN WHICH THE SURFACES OF THE POLYMER PARTICLES ARE INCOMPLETEY COVERED WITH EMULSIFIER AND THE POLYMER CONSTITUENT OF WHICH CONTAINS AT 51 PERCENT BY WEIGHT OF A BOUND BUTADIENE-1,3 HYDROCARBON WHICH COMPRISES ADDING AN AQUEOUS DISPERSION OF AN INORGANIC REINFORCING PIGMENT TO THE SAID BUTADIENE HYDROCARBON POLYMER LATEX, FREEZING SAID LATEX WITH SAID INORGANIC REINFORCING PIGMENT DISPERSION THEREIN TO A SOLID MASS AT A TEMPERATURE ABOVE TEMPERATURES AT WHICH THE LATEX COAGULATES, AND RECONSTITUTING A FLUID LATEX FROM THE FROZEN MASS OF LATEX BY COMPLETELY THAWING THE FROZEN MASS.
