Abstract: A resorcinol-modified phenolic resin composition is formed by reacting a basic catalyst, formaldehyde, water and a benzene-ol to form an intermediate composition to which resorcinol is subsequently added to reduce the presence of free formaldehyde. Optionally, an alkanolamine can be combined and reacted with the resorcinol-modified phenolic resin composition to form a resorcinol-alkanolamine-modified phenolic resin composition. The resorcinol-modified phenolic resin and the resorcinol-alkanolamine-modified phenolic resin compositions can be employed to coat abrasive products having a relatively low free formaldehyde content.

Abstract: A novel filler treatment comprising the preparation of swollen starch compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed. Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch compositions can be prepared in a batch or jet cooker, or by mixing with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch composition is then rapidly mixed with the filler slurry, preferably in a static mixer, and added to the papermaking furnish at a point prior to the headbox of the paper machine.
