Abstract
A composite of polymeric matrix and wood pulp is prepared by masticating such proportion of polymeric matrix as provides a continuous phase and wood pulp having a tensile strength below about 10 kg/cm.sup.2. Water is added if needed to provide the requisite low tensile strength.
Claims9
The method of making a composite of polymeric matrix and wood pulp which comprises masticating such proportion of polymeric matrix including massed polymer as provides a continuous phase, agglomerated wood pulp having a tensile strength below about 10 kg./cm..sup.2 regardless of the direction of measurement and such amount of water as to provide the aforesaid tensile strength, wherein the polymeric matrix is present in an amount of at least 50 parts by weight based on 100 parts by weight of dry wood pulp.
The method of making a composite of elastomeric matrix reinforced with wood pulp which comprises masticating a major proportion of elastomeric matrix, including massed elastomer and a minor proportion, on a dry basis, of agglomerated wood pulp together with water in amount within the range of 35-65% of the sum of the wood pulp plus water.
