## CPC

- C08F 210/14: Monomers containing five or more carbon atoms
- C08F 210/00: Copolymers of unsaturated aliphatic hydrocarbons having only one carbon-to-carbon double bond
- C08F: MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS

## Abstract

Plasticizers are prepared from a monomer mixture consisting essentially of (A) one or more olefins having 6 to 18 carbon atoms and (B) one or more C.sub.1 to C.sub.6 esters or diesters of monoethylenically unsaturated mono- or di-carboxylic acids. Blends of the plasticizers with different polymers, for example polyvinyl chloride, are also prepared.

## Claims

### Claim 1

A blend of about 1 to 600 parts by weight of a plasticizer which is the free radical polymerization product of (A) one or more monoethylenically unsaturated hydrocarbons having 6 to 18 carbon atoms and (B) one or more C.sub.1 -C.sub.6 esters of monoethylenically unsaturated monocarboxylic acids, or diesters of monoethylenically unsaturated dicarboxylic acids, the number average molecular weight being about 500 to 6000, the number ratio of (A) to (B) being about 0.1/1 to 1.5/1, with about 100 parts of different polymer.

### Claim 2 (depends on 1)

The blend of claim 1 wherein the different polymer is selected from the group consisting of polypropylene, polyethylene, polyvinyl acetate, acrylic polymers, polyvinyl butyral, copolymer of poly(vinyl butyral-vinyl alcohol), ethylene-propylene copolymers, butadieneacrylonitrile copolymers, butadiene-styrene polymers, polychloropropene, rigid polyesters, rigid phenolic resins, urea formaldehyde resins, and melamine.

### Claim 3 (depends on 1)

The blend of claim 1 in which 2 to 12 parts of said plasticizer are used per 100 parts of said different polymer.

### Claim 4 (depends on 1)

The blend of claim 1 wherein the different polymer is polyvinyl chloride.

### Claim 5 (depends on 1)

The blend of claim 1 wherein the different polymer is polypropylene blended with or grafted to an ethylene-propylene polymer.

### Claim 6 (depends on 1)

The blend of claim 1 wherein (B) is one or more C.sub.1 to C.sub.6 alkyl acrylates.

### Claim 7 (depends on 6)

The blend of claim 6 wherein acrylates are selected from the group consisting of methyl acrylate, ethyl acrylate, butyl acrylate, and mixtures thereof.

### Claim 8 (depends on 1)

The blend of claim 1 wherein (A) is an olefin of 6 to 12 carbon atoms and (B) is a C.sub.2 to C.sub.4 alkyl acrylate.

### Claim 9 (depends on 1)

The blend of claim 1 wherein polymerization product of (A) and (B) further includes polymerized units of (C) one or more monovinylidene compounds.

### Claim 10 (depends on 9)

The blend of claim 9 wherein the molar ratio of (C) to the sum of (A) and (B) is up to about 0.25 to 1.

### Claim 11 (depends on 9)

The blend of claim 9 wherein (C) is acrylonitrile, a hydroxyalkyl acrylate, or mixtures thereof.
