  • Publication number: 20230265015
    Abstract: The present invention provides fiber cement articles, such as roof tiles having improved impact and hail resistance and methods for making them. The fiber cement articles comprise cement, an optional filler, reinforcing fibers, such as poly(vinyl alcohol) fibers or a mixture of cellulosic and synthetic fibers, one or more core-shell aqueous emulsion polymers having a crosslinked rubbery core with a calculated glass transition temperature (calculated Tg) of from ?20 to ?140° C., and an at least partially grafted acrylic or vinyl shell polymer having a calculated Tg of from 20 to 170° C., and having a Z-average primary particle size of from 55 to 800 nm, or, preferably, from 140 to 650 nm. The solids weight ratio of the crosslinked rubbery core to the shell of the core-shell aqueous emulsion polymer may range from 85:20 to 97:3.

  • Patent number: 6875802
    Abstract: Disclosed are compositions and processes for preparing polymeric materials having polymerizable units derived from at least one C8 to C30 alkyl (meth)acrylate monomer, and at least one chain branching unit. The presence of the chain branching unit suprisingly results in the polymeric composition having non-gelled polymer chains. The polymeric compositions are useful as additives for improving the melt strength of thermoplastic resins.

  • Patent number: 6730734
    Abstract: The invention provides a composition which increases the impact strength and lowers the viscosity of melt processed plastics resins. In particular the invention relates to an impact modifier composition comprising at least one impact modifier and at least one mineral oil and optionally up to 50% by weight of at least one plastics resin. Methods of making such impact modifier compositions are disclosed, together with a general process for combining at least one oil with at least one impact modifier during the impact modifier manufacturing process.

  • Patent number: 5753752
    Abstract: Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain core/shell copolymers having a rubbery, preferably crosslinked core mainly of units derived from butadiene, and an outer shell mainly of a copolymer of styrene and acrylonitrile. Such copolymers do not require the presence of functional groups capable of reaction with the hydroxyl groups of the poly(vinyl alcohol).

  • Patent number: 5744546
    Abstract: Polymers containing a high percentage of vinyl alcohol units are difficult to process into sheet, film, injection-molded objects, or fibers. Such melt-processing is greatly enhanced by admixing certain hydrogenated block copolymers formed by sequential anionic polymerization of butadiene and styrene, followed by hydrogenation, then followed by grafting of maleic anhydride.
